PWM - Pulse Width Modulation

Generating PWM with PIC Microcontroller – MPLAB XC8

Pulse Width Modulation (PWM) is the one of the simple and most commonly used technique to produce analog voltages from digital signals. It has a wide variety of applications such as Digital to Analog Converter (DAC), DC Motor Speed Control, Sine Wave Inverters, Brightness control etc. PWM signals are ON – OFF signals (HIGH or LOW) (hence the name Pulse) whose HIGH or ON duration is changed (hence Width Modulation) in accordance with our requirements. The fraction of time period [...]

Generating PWM with PIC Microcontroller using Hi-Tech C

PWM (Pulse Width Modulation) is a powerful technique used to generate analog voltage using digital signals. It has a wide variety of applications such as controlling average power delivered to a load, generating analog voltage level, sine wave generation and DC Motor speed control. PWM signals are ON-OFF signals (hence the name Pulse) whose ON duration are changed (hence Width Modulation) according to our requirements. The fraction of time period for which the signal is ON to total time period [...]
