Question

A special $PCM$ system uses $32$ channels of data, one whose purpose is an identification (ID) and synchronization. The sampling rate is $4$ kHz. The word length is $5$ bits. Find the serial data rate.

• A. $1280\;kHz$
• B. $160\;kHz$
• C. $320 \;kHz$
• D. $640 \;kHz$

Answer 1

Serial data rate = sampling rate x no. bits/frame = 4 kHz × 32×5 =   640 kHz.
