Q19: A FDM system uses SSB-SC modulation and AM main carrier modulation.
There are forty (40) equal amplitude voice input channels; each bandlimited
to 3.3 kHz. A 0.7 kHz guard band has allowed between channels and below the
first channels.
(a) Determine the final transmission BW.
(b) Compute the degradation in signal- to- noise of input No. 40 when
compared to input No.1, assuming that PSD of noise (two - sided) is
f' uw/Hz.
Ans: 160 kHz, 36 dB.
