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....
