[#71] A terminal multiplexer has six 1200 bps terminals and 'n' 300bps terminals connected to it. The outgoing line is 9600bps. What is the maximum value of n?
Correct Answer

(C) 8

Explanation

Solution: Since there are six 1200bps terminals, 6*1200 + n*300 =9600 by solving this, n=8.

[#72] Maximum data rate of a channel for a noiseless 3-kHz binary channel is
Correct Answer

(B) 6000 bps

Explanation

Solution: Maximum data rate = 2 H log 2 V bps, where H is the bandwidth, V is the discrete levels. Here H is 3 kHz and V is 2. So, data rate = 2*3000 log 2 2 bps = 6000 bps.
