The input r(t) to a DSBSC receiver is a DSB signal s(t) = A m(t)cos (21fet) corrupted by additive white Gaussian noise with two-sided power spectral density N,/2, where No = 10-12 W/Hz, m(t) is a message signal bandlimited to 10 kHz. Average power of m(t) is Pm = 4 W and Ac = 2 mV. The block diagram of the receiver is shown below. Note that the receiver has filters which have slightly larger bandwidths than a typical DSB...
An AM receiver is tuned to broadcast station at 600 kHz. Calculate the image rejection in dB, assuming that the input filter consist of one tuned circuit with a Q of 40? An SSB system transmit a peak envelope power of 100 W into a 75 ohms load. The carrier signal is modulated by two tones, with frequencies 2 kHz and 3 kHz with equal magnitude and only the lower sideband is transmitted with a suppressed carrier. Determine the average...
4.1. Preliminary work Derive an expression for the output of the product detector from the block diagram in Figure 4-1 Product Detector assuming that the input is a single tone modulated DSBSC signal. Also show the effect on the output if the local carrier is out of phase from the modulated carrier by 45 degree. 4. DSB-SC (Suppressed Carrier) Detection Demodulation of DSB-SC signals is achieved by using a product detector as shown in Figure 4-1 Product Detector below. The...
