PWM : Pulse Width Modulation

Pulse Duration Modulation or Pulse Width Modulation is a powerful technique used to control analog circuits using digital outputs. Nowadays PWM has a wide variety of applications such as to create analog voltage level, waveform generation, motor speed control, power control and conversion, measurements and communication etc. PWM uses a rectangular pulse wave as shown in the figure below whose pulse width is modulated, which results in the variation in the average voltage of the waveform. Pulse Width Modulation PWM Period The PWM Period is the time [...]
