What is low-pass band?

A low-pass filter (LPF) is a circuit that only passes signals below its cutoff frequency while attenuating all signals above it. It is the complement of a high-pass filter, which only passes signals above its cutoff frequency and attenuates all signals below it.

What is low-pass and band pass?

A bandpass filter allows signals between two specific frequencies to pass, but that discriminates against signals at certain frequencies. A lopass filter is a filter that passes signals with a frequency lower than a certain cutoff frequency and minimizes signals with frequencies higher than the cutoff.

What is pass band in low-pass filter?

The passband is the region (frequency band) where the filter should pass its input through to its output with unit gain. For a low-pass filter (as shown), the passband reaches from a frequency of zero up to a certain frequency limit.

What is the required bandwidth of a low-pass?

A low pass analog signal with bandwidth of 20 kHz is sampled at nyquist rate and quantized using a 16-level uniform quantizer. The resultant digital signal is transmitted using M-ary PSK with raised cosine pulse (roll-off factor 0.3) shaping of baseband data.
