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
Â
(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.
