Communication systemProblems A 25 MHz carrier is modulated by a 400 Hz audio sine wave If the carrier voltage 4 V and the maximum deviation is 10 KHz, write the equation of this modulated wave for FM. If the modulating frequency is now changed to 2 KHz, all else remaining constant, write the new equation for FM2. In an FM system, when the audio frequency (AF) is 500 Hz and the AF voltage is 2.4 V, the deviation is 4.8 KHz....

1 and 2 please thank you #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...
A communication system has a Gaussian pdf with zero mean, o = 1/2 variance and a bandwidth W = 10kHz with noise power No 10-15 W/Hz. The transmission loss power is 100dB. Calculate the transmitted power, St, to achieve the output signal to noise ratio, (Sp)... = 40 dB for each modulation scheme as listed below. Show your all calculations for each modulation scheme in detail and explain your solutions clearly. SSB b. DSB-LC with modulation index u = 1...
