µ-law encoder:

i. The μ-law encoder inputs 14-bit samples and outputs 8-bit codewords.

ii. The telephone signals are sampled at 8 kHz (8,000 times per second), so the μ-law encoder receives 8,000×14 = 112,000 bits/sec.

iii. At a compression factor of 1.75, the encoder outputs 64,000 bits/sec.

iv. The G.711 …
