Extracted text: Q16: 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 f² µw/Hz. Ans: 160 kHz, 36 dB.
