A 24 signal each of 5kHz base band bandwidth are FDM multiplexed using SSB sub carrier modulation. thecomposite multiplexed signal y(t) is frequency modulated using100MHz carrier frequency. the lowest frequencey of first channel ofthe multiplexed signal is20 kHz and no guard bands between thechannels, assume that each base band signal has th same normalizedpower. the channed with least noise has out put SNR of 50 dB.
a) Find the output SNR of channels No. 10 and No. 24
b) if the acceptable SNR is 35 dB how many channels in the system are usable
