WebStep 3: Design and Construct the 2nd Order Butterworth Low-Pass Filter The final stage, is a low-pass filter to remove all signals that can occur above the highest frequency component of an ECG wave, such as WiFi noise, and other ambient signals that might distract from the signal of interest. Web2 Answers. As you suspect, this paper says that zero-lag Butterworth filtering is obtained by passing the signal through the filter twice: once in the forwards direction and once in reverse. Ok, the paper also mentions that the cutoff frequency needs to be adapted when filters are cascaded.
