Pulse-Width Modulated power supply. Our regulated PWM maintains a high conversion efficiency over an input supply range of 10.5-15 VDC. The result is less demand on the battery, lower (amplifier) operating temperature, and extremely accurate low frequency reproduction.
Modulation method. Signal modulates or alters the duty cycle of the pulse. In PWM, the carrier is a pulse stream. Also called PDM (Pulse Duration Modulation).
Pulse width modulation. The ‘quality factor' of a resonance, the ratio of the frequency at the peak to the bandwidth at its -6dB points.
A control method that varies the pulse width to produce a desired waveform.
Pulse Width Modulation. 1. A PWM controller (amplifier) switches DC supply voltage on and off at fixed frequencies. The length of the on/off interval or voltage waveform is variable. 2. Pulse width modulation (PWM), describes a switch-mode (as opposed to linear) control technique used in amplifiers and drivers to control motor voltage and current. PWM offers greatly improved efficiency compared to linear techniques.
Pulse Width Modulation. A form of digital recording which makes use of the width of a digital pulse.: The sharpness of a peak.
PULSE WIDTH MODULATION. A switching power conversion technique where the on-line (or width) of a duty cycle is modulated to control power transfer for regulating power supply outputs.
Pulse Width Modulation. A method of controlling the average current in a motors phase windings by varying the on-time (duty cycle) of transistor switches. Ramping The acceleration and deceleration of a motor. May also refer to the change in frequency of the applied step pulse train.
Pulse Width Modulation. A modulation which encodes an analog signal into variable-length digital pulses.
Pulse Width Modulation. See Bitstream processing.
The abbreviation for Pulse-Width Modulation. ESCs pulse current to the motor in an ON-OFF manner. Changing the ratio of the ON time to the OFF time changes the speed of the motor. For example, at 80% speed, the current pulse is on 80% of the time and off 20% of the time. This cycle happens 60 times-per-second for low-frequency ESCs, and approximately 2,500 times-per-second in the Novak high-frequency ESCs.
Pulse Width Modulation. A method of voltage regulation used in SMPS where the output is controlled by varying only the width of a train of pulses.
Pulse Width Modulation. A type of chopped DC power where the width of the pulse is varied to control the average voltage (see "chopped DC power").
Pulse Width Modulator: A digital logic circuit that can be programmed to produce a pulse having any desired period or duty cycle. A convenient means of controlling variable speed motors.
A switch-mode control method used in amplifiers and drivers to control motor voltage and current to obtain higher efficiency than linear control. PWM refers to variable on/off times (or width) of the voltage pulses applied to the transistors.
Inverter high-frequency chopping technique using a means of regulation enabling rapid modification of pulse widths over a single period, thus making it possible to maintain the inverter output within tolerances even for non-linear loads.
Pulse Width Modulation. Equivalent to PDM
See Pulse Width Modulation.
Pulse Width Modulation. A signal with a fixed pulse width (frequency), which is turned on for part of the pulse. The percent of time that the signal is on is called its duty cycle. PWM is used to control voltage (and consequently current) to fuel injectors.
Pulse width modulation. An OBDII communication standard used by Ford domestic cars and light trucks. It is one of three hardware layers defined by OBDII.
Pulse Width Modulation a method of representing analog signal levels in digital form by varying the width of the digital pulse. This technique is used for recording the analog Cue Tracks in DASH in the digital tape. First-generation DASH machines like the Sony PCM-3324 used bias recording.
Pulse Width Modulated. PWM inverters are the most expensive, but produce a high quality of output signal at minimum current harmonics. The output voltage is very close to sinusoidal.
Pulse width modulation (PWM) is an efficient electronic control technique used in stepper motor drivers to set average winding current. PWM is commonly used in high power amplifiers and power supplies.
The process of encoding information based on variations of the duration of carrier pulses. Also known as pulse duration modulation (PDM).
pulse width modulation) A conversion method in which the widths of pulses in a pulse train represent the analog information.
