Ch.11 Question 29 in Signals and Systems Analysis Using Transform Methods and Matlab 2nd Edition---- Can I get an explanation for this quickly and as soon as possible please and Thank you.
The causal square wave voltage signal illustrated in Figure E.29 excites five practical passive filters (a)-(e) also illustrated in Figure E.29. The responses of the five filters are illustrated below them in a random order. Match the responses to the filters Excitation 0 6 8 10 Time, t (s) R-10 20246 8 10 2 0 246 810 2 0 246810 2 0 26810 20 2 468 10 Time ts Time,t Time, t 05) Time.ts Time, ts) Figure E.29Explanation / Answer
a -> 5; b -> 4; c -> 1; d -> 2 e -> 3;
The circuits in 'a' and 'e' are low pass filters i.e. as time tends to infinity output is equal to input. Circuit 'a' is with a lower time constant and the response will be fast and circuit 'e' is with a higher time constant and the response will be slow.
The circuits in 'b' and 'c' are high pass filters i.e. as time tends to zero output is equal to input. Circuit 'b' is with a lower time constant and the response will be fast and circuit 'c' is with a higher time constant and the response will be slow.
