Web17 de ago. de 2024 · If you are getting both interference and signal through at an adequate gain without overloading the ADC, then you can use a digital filter after the ADC. There is a trivially simple implementation of a 50 Hz notch that you can apply, either in the MCU or in Python, there's no need to use a relatively expensive FFT operation. WebSimple notch filters – where the gain is unity everywhere either side of the notch – can be very useful, e.g. for suppressing 50 Hz or 60 Hz hum in measurement systems. The passive TWIN TEE notch is well known, and can be sharpened up in an active circuit so that the gain is constant, say, below 45 Hz and above 55 Hz.
