A bandpass filter is needed if only a certain range of frequencies are needed. An example of uses for bandpass filters are audio applications if only certain frequencies are desired to be heard while others should not. This type of bandpass filter is a passive bandpass filter. It doesn't require any power. It is not used for any active ...

The 2-element vector ‘fp’ gives the passband frequency; Examples of Bandpass Filter Matlab. Let us now understand the code of ‘Bandpass filter’ in MATLAB with the help of various examples: Example #1. In this example, we will create a sine signal which is sampled at 10000Hz for 1 second and will pass it through a Bandpass filter.

Modern IF filtering design is the best ever. But the engineer still has to design an audio output that will accommodate the widest signal the radio is designed to copy. Typically, this is 6 kHz for wide band AM or for FM. The audio passband must be capable of passing such signals through.

y = 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.
