IL - Ratio of input power to transmitted power. Loss of power passing through a material which includes reflection and attenuation.
The loss of voltage (or power), as measured in dB, resulting from placing a resistor (or some other power absorbing network or component) between a voltage or power source (amp) and its load impedance (speaker.) It is the ratio of the voltage (or power) absorbed in the load without the resistor (or network) to that when the network is inserted. For example, if the voltage across a load is 2 volts without a network and 1 volt with the network, then the insertion loss is stated as 6 dB.
If the inclusion of an electronic device into a line diminishes the signal's strength, it's called insertion loss.
The loss resulting from the insertion of a device into a transmission line, expressed as the reciprocal of the ratio of the signal power delivered to that part of the line following the device to the signal power delivered to that same part before insertion. Insertion loss is usually expressed in dB. In an optical fiber system, insertion loss is the total optical power loss caused by insertion of an optical component, such as a connector, splice, or coupler.
The attenuation of a signal as it passes through a connector
The attenuation caused by the insertion of a device (such as a splice or connection point) to a cable.
Decrease in power resulting from the insertion of a component or splice in a circuit.
Is a measure of power attenuation at any output port relative to the power at the input port of a passive component.
The loss of the filter, in decibels, measured at center frequency or at the minimum loss point of the passband relative to a thru line (0 dB). It is the combination of dissipation loss and reflection loss.
Loss in signal level that occurs when a device such as a splitter is inserted into the cable network.
Attenuation caused by the insertion of an optical component into an optical transmission path.
Loss of optical power resulting from the insertion of a component or device into the optical path.
The sound level reduction at a given location due to the insertion of a noise control device, expressed in decibels.
The difference, measured in dB, between input power and output power levels when a unit is in low-loss condition.
Attenuation expressed in dB for a particular path through a component. Insertion loss for Gould couplers includes excess loss, coupling loss and polarization effects.
The loss in signal strength due to the insertion of a device in series with a signal path. Typically measured over the intended operating frequency range of the device.
The loss caused by the insertion of a component such as a splice or connector in an optical fiber.
A loss in gain of a system after a component has been added or inserted in the system.
The loss measured in dB of any device that might be connected in series with the antenna cable.
The ratio between the amplitude of the output signal of a device or circuit compared to the amplitude of its input signal. Insertion loss is normally expressed in decibels (dB).
The amount of signal level decrease caused by placing a passive audio device into a system. The crossovers built into all speakers is a good example of a passive device.
Also called “ feed thru loss. ”This is the loss that occurs as signals pass through a passive device. Insertion loss occurs in devices that do not amplify the signal.
Additional loss in a system when a device such as a directional coupler is inserted; equal to the difference in signal level between input and output of such a device.
The loss of signal strength due to the insertion of a piece of equipment in the line.
The loss in power caused by the insertion of a network between a source and a load.
The loss of signal caused by a filter being inserted in a circuit. It has many different definitions and is usually measured in dB. In general, it is the ratio of voltage to the load (at peak frequency response) with the filter in the circuit, to the voltage in the load if a perfect lossless matching transformer replaced the filter. When a filter is inserted between two circuits whose impedance differs widely, it is sometimes more practical to specify insertion loss some other way.
The loss of signal power due to the insertion of a connector or another component in the transmission path. Insertion loss is usually measured in decibels as the ratio of the signal power measured before the component insertion point compared to the signal power measured past the insertion point.
The loss in load power due to the insertion of a component or device at some point in a transmission system. (Generally expressed as the ratio in decibels of power received at the load before insertion of the apparatus, to the power received at the load after insertion.)
Loss of signal strength due to connection to a device.
Measurement reflecting filtering ability. Insertion loss represents the difference in power reception prior to and after the use of a filter.
The difference between the power received at the load before and after the insertion of apparatus at some point in line.
A measure of how much smaller the output signal of a passive device is with respect to the input signal. It is measured in decibels.
The loss in load power resulting from the insertion of a cable, component, or device. It is expressed in decibels as the ratio of power received at the load before insertion to the power received at the load after insertion.
The transmitted power difference between a filter inserted or not
The attenuation of signals due to routing them through a switching module or system. Specified as a decibel value (dB) over a frequency range. Loss could be due to the resistive, inductive or capacitive features of the signal path, or a combination of all of these.
The amount of attenuation provided by a filter.
The signal strength loss that occurs when a piece of equipment is inserted into a line.
The attenuation caused by the insertion of an optical component, such as a connector or a splice, into a previously continuous path.
The reduction of sound power levels reached by inserting a muffler or silencer in an acoustic transmission system.
a term usually applied to silencers which is simply the reduction in noise level achieved by the insertion of the noise control device between the noise source a "receiver" position
The attenuation vs. frequency of a device placed into a circuit, connector, or network. It is usually expressed as the log of the ratio of a voltage before vs. after the device is inserted.
A comparative measurement between the total loss of a circuit with and without the component assembled.
While many definitions exist this one applies to filters. The difference between the power received at the load, before, as compared with after the insertion of a filter network. This loss is usually expressed in dB.
Total amount of signal loss, expressed in dB, caused by a component in the network.
Insertion loss is the measure of reduction in signal magnitude caused by inserting a component, such as a connector, into a previously connected optical path. This measurement allows for analysis of the impact of inserting a single optical component into a system, sometimes called “calculating a loss budget.” Insertion loss is measured in decibels (dB). See also: attenuation, reflectance
The extra optical attenuation caused by the insertion of a component into an optical system.
Total optical power loss caused by insertion of an optical component such as a connector, splice, or coupler into a previously continuous path.
The loss of power that results from inserting a component, such as a connector, coupler (illustrated), or splice, into a previously continuous path.
The amount of signal energy lost when a device is inserted into a communication line. Also known as "feed through" loss.
That property between the input and output of a device causing a predictable signal loss.
In telecommunications, insertion loss is the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber. It is usually expressed relative to the signal power delivered to that same part before insertion. Insertion loss is usually expressed in decibels (dB).
