WebMar 4, 2024 · Pulse width modulation (PWM) is a technique used to precisely control analog devices with a digital signal. A pulse width modulation signal consists of electronic pulses that are used to mimic a changing analog voltage. Pulse width modulation signals are commonly used to control analog devices like servos, LEDs, and DC motors. WebModulation is the D/A conversion in which the digital data is placed on the transmission line by modulation of a tone or carrier. Demodulation is the reverse process. In a data communication system, transmitting and receiving modems are necessary at each end of the analog transmission line. st mary technical high school jamaica address
