A linear time-invariant LTI system is shown in Figure Q1. A signal x_rect is applied at the input of an ideal low pass filter with frequency response H_rect(/4). The filtered signal y is shown.
(i)
Illustrate graphically X, H, and F.

(ii)
Determine the type and the specification of the filter transfer function H, in order to obtain the filtered signal y.
