An interview is held with a student about the importance of education for thirty minutes at a radio station. It was later amplitude modulated & transmitted to receivers on the school campus.The expression below describes the transmitted signal a(z) a(z)= Acos(16πz) where A=3cos(10πz) a. In an expression form, express a(z) as a sum of sinusoids & determine the frequency components of the signal a(z)b.
