MATLAB Online에서 열기 Hello everyone, I'm trying to high-filter a signal beacause when I perform a fft of the original signal I find a contribution at very low frequency even if I take the fft of detrend(signal). I want to cut out that contribution. I wrote this simple script...

HPF = dsp.HighpassFilter(Name=Value) Description HPF= dsp.HighpassFilterreturns a minimum order FIR highpass filter,HPF, with the default filter settings. Calling the object with the default property settings filters the input data with a stopband frequency of8kHz, a passband frequency of12kHz...
I think the error you get is due to the nature of the sample you use, maybe its RGB image, if so you need to change it to grayscale image or process each channel individually, try this as first attempt :
