Answer 1

19. False.......as the filter of a large order has a narrow transition band.

20 True

21. True   Linear phase is a property of a filter, where the phase response of the filter is a linear function of frequency. ... For discrete-time signals, perfect linear phase is easily achieved with a finite impulse response (FIR) filter

22. b

rest is correct
