WebA: Passband is the band of frequencies of the input signal that passes through the filter with an attenuation of less than 3 dB attenuation, while stopband is a band of frequencies of the input signal that are blocked or more highly attenuated by the filter. What is the difference between bandpass and passband? Weby = bandpass(x,wpass) filters the input signal x using a bandpass filter with a passband frequency range specified by the two-element vector wpass and expressed in normalized units of π rad/sample. bandpass uses a minimum-order filter with a stopband attenuation of 60 dB and compensates for the delay introduced by the filter.

"WebThe stopband attenuation ranges from A O to the A SB (stopband magnitude). A O (passband gain) and A SB along with the specified stopband attenuation, defines the speed of the notch’s attenuation. Finally, for Chebyshev approxi-mations, the definition of the ripple magnitude is R P. The bandpass/notch filter requires pairs of poles and " - Filter stopband attenuation
