cosine wave

In Section 3-2.2, we discussed a simple example of the "beating" of one cosine wave against another. In this problem, you will consider a more general case. Let

For the case discussed in Section 3-2.2, the amplitudes are equal, A = =1.

(a) Use phasors to obtain a complex signal z(t) such that

 

(b) By manipulating the expression for z(t) and then taking the real part, show that in the more general case above, x(t) can be expressed in the form

and find expressions for C and D in terms of A and B. Check your answer by substituting A = B = I.

(c) Find values for A and B so that

Plot the spectrum of this signal.
