5 Questions
What are the three processes of Pulse Code Modulation (PCM)?
The three processes of Pulse Code Modulation (PCM) are sampling, quantization, and encoding.
What is the result of sampling in Pulse Code Modulation (PCM)?
The result of sampling is a series of pulses with non-integer amplitudes between the two limits (Vmin and Vmax).
How is quantization performed in Pulse Code Modulation (PCM)?
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.
What are the values of Vmin, Vmax, and L used in the quantization process?
Vmin = -20, Vmax = +20, L = 8 are the values used in the quantization process.
How is the quantization code encoded in Pulse Code Modulation (PCM)?
The quantization code is encoded as streams of bits.
