2. Pulse-width modulation - Wikipedia

   en.wikipedia.org/wiki/Pulse-width_modulation

   Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an

3. Pulse-frequency modulation - Wikipedia

   en.wikipedia.org/wiki/Pulse-frequency_modulation

   Comparison of PFM (top) and PWM (bottom) of a signal that starts at a constant low value and then transitions to a constant high value. Pulse-frequency modulation ( PFM ) is a modulation method for representing an analog signal using only two levels (1 and 0).

   The following table compares cathode-ray tube (CRT), liquid-crystal display (LCD), plasma and organic light-emitting diode (OLED) display device technologies. These are the most often used technologies for television and computer displays.

5. Chopper (electronics) - Wikipedia

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

   Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors.

6. Random pulse-width modulation - Wikipedia

   en.wikipedia.org/wiki/Random_pulse-width_modulation

   Electromagnetic interference (EMI) filters have been widely used for filtering out the conducted emissions generated by power converters since their advent. However, when size is of great concern like in aircraft and automobile applications, one of the practical solutions to suppress conducted emissions is to use random pulse-width modulation (RPWM).

   A thyristor dimmer rack An electrical schematic for a typical SCR-based light dimmer Solid-state , or semiconductor , dimmers were introduced to solve some of these problems. Semiconductor dimmers switch on at an adjustable time (phase angle) after the start of each alternating-current half-cycle, thereby altering the voltage waveform applied ...
