Without undertaking a full analysis, it looks like you either want to filter the signal, or take and hold it for a period before gathering another sample. The first can be achieved using the mathematics or ramp functions. The second by sending the raw signalto aMux that outputs to an amplifier that in turn feeds back into the mux. A timer set to your desired interval then switches the mux to takeactual samplefor one scan and then outputs the same value for remaining scans.See attachment.

Hi WaW, search "filter logo" and look my answers..you can find some older circuits from me to filter signals (by calculate amean value). At the german forum part i have build a summary of all my circiuts to filtering analog signals at "Hinweise zu Maßnahmen bei schwankenden Analogeingangswerten (z. B. Temperatur-Messwerten)" |
