Unformatted text preview: What are the frequencies of Class95 FM and other FM broadcasting stations? 4 (a) Sketch the input spectrum. See if aliasing has happened. (b) Sketch the relevant spectra carefully take the frequency to be positive first and use the fact that the signal is real. 5 (a) Express the output in terms of the input spectrum. Use the inverse transform formula to work out the output and input at time 0 first see that they are related. (b) Any implication on the bandwidth of the input? 6 (a) Recall the result of the simulation program that shows the spectrum of 2 sinusoids in noise....
