Answer #1

Baseband transmission of a digital signal is possible only if we have a low pass channel

The correct option is a.

a) low-pass

Explanation

Baseband transmission of a digital signal that preserves the shape of the digital signal is possible only if we have a low-pass channel with an infinite or very wide bandwidth

b) Bandpass

If the available channel is bandpass, we cannot send the digital signal directly to the channel, it must be converted to an analog form before transmission.

c) low rate: low rate channel doesn;t make any sense in this problem.

d) high rate: Baseband transmission of a digital signal is possible only if we have a high rate channel because high rate show the data rate.

In this problem, we study a simple noisy communication channel. Suppose that X is a binary signal that takes value −1 and 1 with equal probability. This signal X is sent through a noisy communication channel, and the medium of transmission adds an independent noise term. More precisely, the received signal is Y=X+N, where N is standard normal, indpendendent of X. The decoder receives the value y of Y, and decides whether X was 1 or −1, using the following...
