Discuss
Answer & Solution
Answer: Option B

As all lines are full-duplex and there are no self connections, only the cross points above the diagonals are needed. Hence formula for the number of cross points required is n(n-1)/2.
12
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?
Discuss

Answer: Option C
Solution:

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

13
Maximum data rate of a channel for a noiseless 3-kHz binary channel is
Discuss
Answer & Solution
Answer: Option B
Solution:
Maximum data rate = 2Hlog2V 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 log22 bps = 6000 bps.
