Figure shows a pair of pulses that are orthogonal to each other over the interval [0, T]. In this problem we investigate the use of this pulse-pair to study a two-dimensional matched filter.a) Determine the matched filters for the pulse s1(t) and s2(t) considered individually; Form a two-dimensional matched filter by connecting the two matched filters of Part a) in parallel, as shown in figure below. Hence, demonstrate the following: b) When the pulse s1(t) is applied to this two-dimensional filter, the response of the lower matched filter is zero. c) When the pulse s2(t) is applied to this two-dimensional filter, the response of the upper matched filter is zero.
