#103623 - median filter, simulate algo on PC Responding to: ???'s previous message |
Hi Thakkar,
I'd suggest recording the ADC data to a PC and simulating the algorithm(s) there. Depending on the nature of your data (periodic, non periodic, gaussian, single breakouts) some algorithms will be better for you than others. You might find a median filter (read f.e. 5 values, sort them, then take the middle one) to give good and robust results. Note, an algorithm can't do wonders (RMS of your readings will typically drop with sqrt(Number_of_Readings)) so time spent for an analog input filter (like the one suggested by Kai Klaas) is probably spent well. Greetings, Frieder |
