Complete solutions please!
1. Fourier Transform of a Beat. Consider a time signal of a beat, given by: f(t) = A? cos (wit) + A? cos (w?t) (1) where A? and A2 (coefficients) and w? and w? (angular frequen- cies) are constants, and w? w2. Find the Fourier transform F(w) of this signal. NOTE: The variable w is not equal to either of the constants w? and w2. HINT: You may need to remember and use the definition of the Dirac delta function as an integral. [10 points]
