A normalized message signal has a bandwidth of W = 10 KHz and a power of Pm= 0.75 . It is required to transmit this signal via a channel with an available bandwidth of 80 KHz and attenuation of 50 dB. The channel noise is additive and white with a power-spectral density of N0/2 = 10^(-10) watts/Hz. A frequency-modulation scheme, with no pre-emphasis/de-emphasis filtering, has been proposed for this purpose. 1. If it is desirable to have an SNR of...

Consider a message signal m(t) with bandwidth W = 5.86 kHz. This signal is applied to a product modulator, together with a carrier wave c t = cos(210000πt) producing the DSB-SC modulated wave s(t). This modulated wave is next applied to a coherent detector producing an output signal y(t). The coherent detector consists of a product modulator that multiplies s(t) by c r = 2cos(222000πt) and a low pass filter which has a cut off frequency 21 kHz. The output...
