Could I please have the worked solution for the following question:

(a) A matched filter is known to be used for signal detection in radar. Describe how the matched filter detection technique works. (b) For the time limited digital signal x[n]=[4,3,2,1] Write down the difference equation of the causal, minimum-delay matched filter for the signal. (c) Calculate the output sample values from the matched filter when the signal is delivered to the input. At what instant does the peak output value occur
