Understanding Pulse Code Modulation by blzz2net is a document available to read on EtoBox.
Pulse code modulation (PCM) samples an input signal at a sampling frequency, quantizes the sample levels into digital values using an analog-to-digital converter, and encodes the quantized samples into binary words. At the receiver, the binary words are decoded back into analog signal levels, low-pass filtered to reconstruct the original signal with some quantization error. The quantization error can be reduced by increasing the number of quantization levels and bits per sample, but this increases the requi
