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?
