Q2. In a multiplexed communication system, the physical pathway that carries the combined signal from the multiplexer to the demultiplexer is called the:

💡 Difficulty: medium | ✅ Correct: C

Q3. A Time Division Multiplexing system combines 8 input channels, each operating at 64 kbps, with 1 framing bit per frame. If each slot carries 8 bits, what is the total output data rate, and what percentage of the total bandwidth is used for framing overhead?
