WebJun 5, 2024 · I am using 6th order Butterworth bandpass filter to extract the 10-20 Hz band from the signal (x). After that, I applied the filtfilt command on to the Butterworth bandpass filtered signal (10-20 Hz) to remove the phase delay. Is that I am doing right? Thanks in advance. The code is given below. Feel free to correct the code. WebMay 22, 2024 · The n th-order lowpass filters constructed from the Butterworth and Chebyshev polynomials have the ladder circuit forms of Figure 2.7.1 (a or b). Figure …
