WebApr 10, 2024 · The goal is to be able to find the peaks without having to visually inspect the files to determine if they are reversed or not. I want to find a way to either: i) to determine if the ECG is inverted. If it is inverted I can use -ecg and then find peaks or ii) find a way to determine peaks regardless if they are positive or negative.

WebStep 5: Bilinear Transform from CT BPF to DT BPF The last step is to take H BPF(s) and perform the substitution s! 2 T d 1 z 1 1 + z 1 using T d = 1 as decided earlier. Matlab has a built-in command to do this called bilinear. All we need to do is [num,den] = bilinear(B_BPF,A_BPF,T); to get the nal discrete-time bandpass lter. D. Richard Brown ...
