Q4/ If figure (1) is the spectrum of the periodic signal answer the following for one period of this signal in time domain: - f kHz 12.5 -12.5 -1 Fig. (1) 1- Find the rated sampling frequency and draw the sampled signal. 2- Draw the sampled signal if it sampled at four time of its sampling rate. 3- If this signal modulated by PAM within bandwidth needed not greater than (0.5 Fs), draw the (flat top) output signal. 4- Draw the P WM output for this signal. 5- Draw the PPM output for this signal. 6- If the PCM are used with S/N ratio not less than (25.84dB), calculate the required bandwidth and draw the output signal for the PCM system with (RZ) line coding. 7- If the L (even parity) error detection system are used, calculate the transmitted data and the required bandwidth. 8- If the V (even parity) error detection system are used, calculate the transmitted data and the required bandwidth. 9- If the L&V (even parity) error detection system are used, calculate the transmitted data and the required bandwidth. 10- If CRC error detection system are used which detect 8 error with 100% percent, state the polynomial and calculate the required bandwidth.
