Question

7. Nyquist's Call (10 Points) On one side of a telephone call (master) there is a buzzer playing a note at 11,004 Hz. On the other side (remote) is a crystal glass with a resonant frequency of 3004 Hz. The telephone is a band-limited digital system that samples at 8000 Hz. A. If the buzzer's note (treat it as a pure tone or sine wave) is played, will the glass shatter on the other side? (Please remember to briefly justify] B. Now if we add a whistle at 4,996 Hz, will this make a difference? [Please remember to briefly justify]

Answer 1

Thus, adding a whistle at 4,996 Hz will cancel the 3004 HZ frequency team and saves the gilases from breaking.
