Hello to every body,
I´m trying to make audio measurements with a microphone on a noise machine. After I will analize it with a dsp.
I´m having problems with some noise in low frecuencies.
I would like to find an active high pas filter integrate with tuenable frecuenci fc 200hz for example but with a good order on the filter (like 4 or 8). If it is a band pass filter for audio is also ok.
Many thaks for your help
