Q4:Channel 1 of two channels PAM system handles 8KHZ signal : Channel 2 handles two channels are sampled at equal intervals of time using very nurrow puises at the lowest frequency that is theoretical adequate The sampled signals are time multiplexed and puassed through a L.PF before transmission. What is the minimum clock frequency of the PAM system? What is the minimum cut off frequeney of LPF used before transmission that will preserve the amplitude information on the output pulses. What would be the minimum bandwidth if these channels were frequency, multiplexed.using i) ii) iii) hnion

Amplitude modulation

A radio signal can carry information in the form of sound or image for broadcasting or communication. For it to be sent to a greater distance, the signal must be changed or modulated in some way. One of the easiest way is to change the amplitude of the signal with variations of the video or the audio signal. This is called Amplitude Modulaton. In this modulation information of message is carried in amplitude of carrier signal.
