The standard pulse shape used in most short-distance cable communication applications such as RS232 is a rectangular pulse.
(a) The matched filter receiver for the rectangular pulse transmission is usually implemented with an integrate-and-dump circuit. Prepare a block diagram for this receiver, and explain how it works and why it is a matched filter
b) If the voltage used for the amplitude of the pulses is ±A volts, the data rate is R, and the variance of the received noise is N0, determine the signal-to-noise ratio after sampling at the receiver.
(c) An integrate-and-dump circuit can be implemented with a simple RC low-pass filter and a switch. Sketch the circuit diagram for this matched filter receiver.
