The image below shows the settings in the filterDesigner by using Chebyshev type II bandpass filter and the plots. The image below shows my hand code in MATLAB using the same settings for Chebyshev II bandpass filter. The plots are below and look different...
This MATLAB function 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.
Toolbox™ enables you to quickly filter signals. You can usedesignfiltand other algorithm-specific (butter,fir1) functions when more control is required over parameters such as filter type, filter order, and attenuation. For more information onfilter designwith MATLAB, seeSignal Processing Toolbox...

The quality factor, or Q factor of a filter is the ratio of its peak energy to bandwidth. Because shrinking or stretching the frequency support of a wavelet results in commensurate increases or decreases in its peak energy, wavelets are often referred to as constant-Q filters....

I am using the PIC33 DSC microcontroller, example CE005_FIR_DSP_lib_Filter, I do not understand how filter taps are generated. Taking the bandpass example for instance. Files from the demo: FILTER SPECIFICATION FILE FILTER TYPE: BAND PASS 3H PASSBAND RIPPLE IN -dB -.1000E-01 STOPBAND ...
Bandpass filter for images (2D arrays) supressing high-frequency noise, low-frequency variations, and stripes. Gaussian, Butterworth, or hard filter options. To use: call function imbandpass(image, low_cutoff, high_cutoff), returns smoothed image. The default options of Gaussian filter, Gaussian...
This MATLAB function transforms an analog lowpass filter prototype with unity cutoff frequency (1 rad/s) into a bandpass filter with center frequency Wo and bandwidth Bw.
