Question

1 and 2 please

#1) (3 pts.) The commercial FMGFCC regulated) station uses A-30 kHz to broadcast FM meas find the blank (unused) frequency space. #2) (3 pts) If the commercial FM station uses(FCC regulated) Af= 30 kHz to broadcast FM stereo, find the modulation index #3) (4 pts.) The front-end filter of a radio passes the broadcast FM band from 88MHz to 108MHz. The radio input has an effective resistance of 300 2. What is noise voltage that we would expect to observe due to this resistance? Note: Room temperature is 300'K and Boltzmann's constant is 1.38x10JK. #4) (4 pts.) The following s(t) is given, let t-10 MHz, and k,-10 Sketch PM wave in t-domain, you must find fa& fain (your plot should be clean and clear fortto) Sut)

thank you
