In this problem we wish to develop a base band (low pass equivalent model) for a Costas

Question:

In this problem we wish to develop a base band (low pass equivalent model) for a Costas PLL. We assume that the loop input is the complex envelope signal

x̃(t) = A_c m(t) e^jϕ(t)

and that the VCO output is e^jϕ(t). Derive and sketch the model giving the signals at each point in the model.
