Last Digit of id=8.

Please solve the question quickly.

The bandwidth of the no-periodic signals contains continuous frequencies. A non-periodic 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 XV Here, X is the last digit of your id. Now, (1) Find the highest frequency and bandwidth. (ii) Draw the frequency domain spectrum
