seven signals are time multiplexed. The output signal is TDM-PAM signal. The output time frame is as shown. If each signal is bandlimited to 1kHz, and the sampling frequency is 25% above the minimum sampling rate. 4 marks fm = 1 KHZ المسافة القامة] a. Calculate the bandwidth. (assume that the guard band is equal to the pulse width) b. If this signal is modulated using high frequency carrier, find the RF bandwidth needed to transmit the signal. patalan الاطار الزمني 1 seven signals are time multiplexed.
