FIR filters are inherently stable. They can be designed to have a linear phase that introduces a delay in the filtered signal while maintaining the waveform shape. However, these filters can have long transient responses and might prove computationally expensive in certain applications. MATLAB can he...
Thebandpass(link) and similar functions were introduced inR2018a. It uses an elliptic filter design, so you can duplicate its design with theellipord(link) and related functions. Remember to use thefiltfiltfunction to do the actual filtering. ...
But it seems, with your spektrogram, filtering might not even be necessary too finde the bigining time and end times of the sine signals. Mathieu NOE 2020년 12월 10일 With STFT (short time fourier transform) , which is the basement of spectrogram, it may be difficult to obtain ...

Bandpass Filtering of Sinusoids Bandpass filter a discrete-time sine wave signal which consists of three sinusoids at frequencies, 1 kHz, 10 kHz, and 15 kHz. Design an FIR Equiripple bandpass filter by first creating a bandpass filter design specifications object, and then designing a filter using...

(4) obtaining a filtered signal sf: the filtered signal is obtained according to a function that sf is equal to fftfilt (h, s), sf is the filtered signal, fftfilt is a function for signal filtering in the MATLAB, h is the filter coefficient obtained in the step (3), and s is an...

The filtering rejects the negative-frequency portion of the pass-band signal (which is shifted in the base-banding operation to reside about frequency −2fc) as well as any noise and interference that could alias into the band of interest during decimation. If a real signal is desired as ...
3. How to design the whole filtering process in Matlab's Simulink to show that the filterbank works (I need to input a signal, filter it and measure the RMS - only then it can really be successful)? What blocks should I use? Thanks for all your help and sorry for stupid questions....
