For example, if you need to design a band pass filter with a lower cutoff frequency 500 Hz and a higher cutoff frequency of 600 Hz and at a sample rate of 1500 Hz, then the second argument to the butter function should be [500 600]/750. Please refere to the documentation of butter ...
The matlab code is like below. function [ fIltSignal ] = op_filter( signal,filtType,sampFreq,freqCut,freqCen,freqBand,filtOrder,graph) switch filtType case 2 % high pass filter (butterworth type) Wn=freqCut; Fn=sampFreq/2; [b,a]=butter(filtOrder,Wn/Fn,'high'); fIltSignal=filter(...

In Malb I used to create the filter coefficients using butter() and then apply those to the signal through filtfilt(). As filtfilt() perform forward and backward direction the filtering, this was useful to have a zero-phase shift filter. DO you know if this is possible in Simulink?The...
There is only a problem when I am generating lowpass and highpass filters. Is there any way to generate a correct HDL code for this filter? Please correct me if any of the steps I am doing are wrong. 0 Comments Sign in to comment. Sign in to answer this question....
