PULSE TIME MODULATION , Pulse Width Modulation (PWM) , Frequency Spectrum for PWM Wave
Digital electronicsadminFrequency Spectrum for PWM Wave , Pulse Width Modulation (PWM) :- PULSE TIME MODULATION In pulse time modulation, the signal to be transmitted is sampled as in pulse amplitude modulation (PAM). In pulse time modulation, amplitude of pulse is held constant, whereas position of pulse or width of pulse is made proportional to the amplitude of signal at the sampling instant. There are two types of pulse time modulation, viz. Pulse Width Modulation (PWM) and Pulse Position Modulation (PPM). Because in both PWM and PPM, amplitude is held constant and […]
