Pulse Code Modulation (PCM) EEE
Pulse Code Modulation (PCM) is a method for digitally representing analog signals by sampling, quantizing, and encoding them into a binary stream of 1s and 0s, widely used in audio (CDs), telephony, and computers. It converts continuous analog waveforms into discrete, coded pulses, offering high noise immunity and allowing for efficient, long-distance, high-quality digital transmission.
