Communication Channel A particularly interesting communication channel can be modeled as a linear, time-invariant system. When the transmitted signal x (t) is a pulse, the received signal r (t) is as shown (Figure 2.22).

a) What will be the received signal when the transmitter sends the pulse sequence (Figure 2.23) x1 (t)?

b) What will be the received signal when the transmitter sends the pulse signal (Figure 2.23) x2 (t) that has half the duration as the original?
