Description : Four channels are multiplexed using TDM. If each channel sends 100 bytes/second and we multiplex 1 byte per channel, then the bit rate for the link is ............... (A) 400 bps (B) 800 bps (C) 1600 bps (D) 3200 bps
Last Answer : (D) 3200 bps Answer: D Explanation: The multiplexer is shown in the Figure. Each frame carries 1 byte from each channel; the size of each frame, therefore, is 4 bytes, or 32 bits. Because each ... channel, the frame rate must be 100 frames per second. The bit rate is 100 32 = 3200 bps.
