  2. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    Duty cycle is expressed in percent, 100% being fully on. When a digital signal is on half of the time and off the other half of the time, the digital signal has a duty cycle of 50% and resembles a "square" wave. When a digital signal spends more time in the on state than the off state, it has a duty cycle of >50%.

  3. Duty cycle - Wikipedia

    en.wikipedia.org/wiki/Duty_cycle

    The duty cycle is defined as the ratio between the pulse duration, or pulse width and the period of a rectangular waveform Spectrum in relation to duty cycle. A duty cycle or power cycle is the fraction of one period in which a signal or system is active. [1] [2] [3] Duty cycle is commonly expressed as a percentage or a ratio. A period is the ...

  4. Servo control - Wikipedia

    en.wikipedia.org/wiki/Servo_control

    Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...

  5. Random pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Random_pulse-width_modulation

    In RPWM, one of the switching parameters of the PWM signal, such as switching frequency, pulse position and duty cycle are varied randomly in order to spread the energy of the PWM signal. Hence, depending on the parameter which is made random, RPWM can be classified as random frequency modulation (RFM), random pulse-position modulation (RPPM ...

  6. SAE J1772 - Wikipedia

    en.wikipedia.org/wiki/SAE_J1772

    The PWM duty cycle of the 1 kHz CP signal indicates the maximum allowed mains current. According to the SAE it includes socket outlet, cable and vehicle inlet. In the US, the definition of the ampacity (ampere capacity, or current capacity) is split for continuous and short term operation. [ 30 ]

  7. Pulse-frequency modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-frequency_modulation

    Pulse-frequency modulation (PFM) is a modulation method for representing an analog signal using only two levels (1 and 0). It is analogous to pulse-width modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave .

  8. Chopper (electronics) - Wikipedia

    en.wikipedia.org/wiki/Chopper_(electronics)

    The average output voltage is directly proportional to the ON time of chopper. The ratio of ON time to total time is defined as duty cycle. It can be varied between 0 and 1 or between 0 and 100%. Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a technique used to encode a message into a pulsing signal.
