Pulse code modulation is a method that is used to convert an analog signal into a digital signal so that a modified analog signal can be transmitted through the digital communication network. PCM is in binary form, so there will be only two possible states high and low (0 and 1). We can also get back our analog signal by demodulation.

Pulse Code Modulation Pulse Code Modulation (hereinafter referred to as PCM) is a sampled modulation similar to Pulse Amplitude Modulation. Pulse-code-modulation (PCM) encoding of digital audio signals has had a long and successful history in the era of the Compact Disc (CD). 0000022916 00000 n In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. No information is lost, but the energy is redistributed in the frequency domain. Pulse Code Modulation (PCM) is different from Amplitude Modulation (AM) and Frequency Modulation (FM) because those two are continuous forms of modulation. 0000073874 00000 n 0000003318 00000 n This book introduces Radio Frequency Source Coding to a broad audience. 0000129630 00000 n 0000128383 00000 n 8.
