Web21 de out. de 2013 · This is pretty easy to do with decimate or so: x_dec = decimate (x, 5). Try to solve your problem in a slightly different way. If you read the manual for decimate, you see that it actually does some low-pass filtering with a cut-off frequency at Fc = 0.8*Fsample/ (2 * downsample_ratio). This is necessary to avoid aliasing problems. WebExample #3. In the above 2 examples, we used a three-channel signal, in this example, we will use a 2-channel signal and will pass it through a Bandpass filter. Below are the …

The order of your filter is too high for the design type with a cutoff frequency that low, so you get numerical problems. To make a quick fix, reduce the order of your Butterworth filter to something a little lower than 10. An 8th order filer works for your design, or raising the cutoff frequency also results in real valued output.
