Ability of an amplifier or loudspeaker to follow accurately abrupt changes, such as the sudden burst of sound generated by an instrument. Good transient response is vital to "clear" or "crisp" overall sound.
The short-term response of an instrument caused by a change of status of the instrument's environment. For example, the switching of a power supply on and off will send very short-term power spikes that can be detected by a volt meter with sufficiently rapid response time.
The response of a circuit to a sudden change in an input or output quantity. In power supplies, this is the excursion of the output voltage and the time it takes to recover from a step change in the output load or the input voltage.
the ability of a speaker to respond to any sudden change in the signal without blurring (smearing) the sound. A speaker that can react quickly to rapid changes in sound has “good transient response”.
the type of neural response that occurs only at the onset or offset of a stimulus. See also sustained response.
How quickly a microphone diaphragm, speaker or other vibrating mass reacts to an input waveform.
The ability of a circuit or device to reproduce transients without distortion.
a temporary condition involving a changing voltage or current that exists only until a steady-state value of either voltage or current is reached
The ability of an amplifier to handle sudden changes in audio levels without distortion.
A measure of the time domain response of a system, input-to-output, to a very brief transient signal at its input. It is widely believed that the time-domain behavior of a device is independent of the frequency response. However, the Fourier transform of this time-domain waveform is the frequency-domain transfer function. See: Impulse Response, Transfer Function, Fourier Transform, FFT.
The ability of a device to respond to a rapidly changing input.
The response curve over time of a control system or process reacting to a step change in the set point or process load.
Response to signals whose amplitudes rise very quickly, such as drum beats and waveforms from percussive instruments.
The response of a lowpass filter to a step function or very low frequency square wave. If a sudden voltage rise is applied to a lowpass filter, the output will respond sometime later. Transient response can also apply to a bandpass filter responding to a sudden burst of signal within its passband.
The ability of an audio component to quickly respond to the signal being fed to it. Transient response is more critical in mechanical components like speakers, phono cartridges, and microphones. See also Tone burst.
The response of a converterÕs output voltage to a defined, abrupt change in either the output current or the input voltage.
The ability of a component to respond quickly and accurately to transients. Transient response affects reproduction of the attack and decay characteristics of a sound.
The ability of a circuit to faithfully reproduce a transient applied to its input.
Time required for output voltage to return to regulated value after a step change of output current, usually specified in microseconds for a specified percentage of load change.
The ability of an amplifier, cartridge or speaker to follow sudden changes in amplitude.
In electrical engineering, a transient response or natural response is the electrical response of a system to a change from equilibrium. A simple example would be the output of a 5 volt DC power supply when it is turned on: the transient response is from the time the switch is turned on and the output is a steady 5 volts. At this point the power supply reaches its steady-state response of a constant 5 volts.
