Unformatted text preview: low = 0). Since a digital signal is a composite analog signal with infinite BW, the idle case is to have low-pass channel with infinite bandwidth (not in real life!). Yet, we can still send only the signal’s frequency components with significant amplitudes within some acceptable threshold for minimum distortion and receive a reasonably acceptable digital signal at the receiver. As the bit rate increases, the signal significant BW (BW ss ) increases, hence we need a wider medium low-pass wider BW (BW m ) For safe digital signal reception: BW m >= BW ss...
