First-order Low-pass RC Filter Analysis
The first-order low-pass RC filter shown in figure 1 below represents all voltages and currents in the time domain. It is of course
possible to solve for all circuit voltages using time domain differential equation techniques, but it is more efficient to convert the
circuit to its s-domain equivalent as shown in figure 2 and apply Laplace transform techniques.

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?
