Easy Bandpass Filter软件

Simplified band-pass filtering without external toolboxes.

软件应用简介

It performs band-pass filtering of a time series with the rectangle window in frequency domain, “without external toolboxes”. An example code is given as follows to filter a time series in the pass band of 200~300 Hz: 

Fs = 1000; 

t = linspace(0,1,Fs); 

x = cos(2*pi*100*t)+0.5*randn(size(t)); 

y = bpfilt(x,200,300,1000);
