1. a) The bandwidth of the nonperiodic signals contains continuous frequencies. A nonperiodic composite signal has a lowest frequency of 200+X, with a middle frequency of 320-X kHz and peak amplitude of (20+X) V. The two extreme frequencies have an amplitude of X V Here, X is the last digit of your id. Now, (i) Find the highest frequency and bandwidth.(ii) Draw the frequency domain spectrum.

* X = 1 ( last digit of my id )
