1. (a) A periodic signal f(t) has a period To. Write the relationship between f(t) and To. (b) An amplitude modulated signal x(t) can be represented by x(t) = A [1 + cos (wot)]cos (wet), where A and wo are constants. (i) Show that the signal is a periodic signal. (ii) Using the definition of the period of a periodic signal, find the period of the signal. (c) Above signal x(t) can be represented as a summation of waveforms x(t) = En=0 An cos(wit) + B₂ sin(wrt). (i) Find the value of wT. (ii) Find the values of A, and B, for n = 0, 1, 2, ......, 00.
