Pulse Code Modulation (PCM) Quiz

The three processes of Pulse Code Modulation (PCM) are sampling, quantization, and encoding.

The result of sampling is a series of pulses with non-integer amplitudes between the two limits (Vmin and Vmax).

Quantization is performed by dividing the range into L zones, assigning quantized values of 0 to L-1 to the midpoint of each zone, and approximating the value of the sample amplitude to the quantized value.

<p>Vmin = -20, Vmax = +20, L = 8 are the values used in the quantization process.</p> Signup and view all the answers
