A.15 Consider a communication channel, transfer characteristic of which is defined
by the nonlinear relation, y(t) = x(t) + x² (t), where x(t) is the input and y(t) is the
output. Assuming the input is an FM signal, x(t) = cos (2лft+(t)), find y(t). Is
it possible to retrieve x(t) from y(t)? If so, how?

The input impedance of this antenna is 75 ohms, and it is attached ɔ a 50-ohm transmission line. The receiving antenna has an impedance mismatch at its terminals, - which leads to a VSWR of 2. The receiving antenna is about 95% efficient and has a field pattern near the beam maximum given by E, = (2âx + jây) F, (0, 0). The distance between the two antennas is 4,000 km, and the receiving antenna Directivity is 100. Determine the Minimum power Delivered to receiving antenna. 1arrow_forward
