Good afternoon forum users, there is not a clean signal. In matlab, I processed the signal using high-frequency and low-frequency filters, everything is ok. I am writing a NodeJS application to record and display a signal. Everything worked out with the recording and display, but not so much with the purity of the signal. Are there any classes, libraries, packages in Arduino or NodeJS that implement the capabilities of DSP (digital signal processing) tools?
