Can You Distinguish Between A Low-pass Channel And A Band-pass Channel.?
Low-pass has one threshold frequency. Band-pass has two threshold frequencies.
Low pass channel which start from 0 frequency mean low frequency.
A low-pass channel has bandwidth with frequency between 0 and infinity where band-pass channel has bandwidth with frequency between f1 and f2
