I'm new here, I have a simple envelope detector model designed on simulink following these instructions: https://www.mathworks.com/help/dsp/ug/envelope-detection.html?searchHighlight=envelope&s_tid=srchtitle_support_results_5_envelope. I tried but the input signal's envelope still shows unwanted word parts at the beginning and end of the envelope (I marked it in red in the image below). Does anyone know where my design problem lies? I spent 2 days with it and still no progress. We hope to receive your help. Thanks a lot
The simulink model and file m contains the filter coefficients is attached below. I hope someone can help me solve this problem, it's very important to me. Sorry for disturbing
