4. Is bandpass a low pass filter?

What is low pass equivalent of bandpass signal?

phasor = equivalent lowpass signal representing the sinusoid (that's why we used the subscript l – for lowpass). Note that this equivalent lowpass signal is complex valued, whereas the bandpass signal (the sinusoid) it represents is real valued.

What is the result of passing white noise through a narrow band pass filter?

Filtering a wide-band (white) noise with a band-pass filter results in narrow-band noise, which is of course the traditional masking stimulus.

What is the difference between lowpass and bandpass?

Unlike the low pass filter which only pass signals of a low frequency range or the high pass filter which pass signals of a higher frequency range, a Band Pass Filters passes signals within a certain “band” or “spread” of frequencies without distorting the input signal or introducing extra noise.

Is bandpass a low pass filter?

A band pass filter is a combination of a high pass and an LPF. It allows only a selected range of frequencies to pass through.
