SUMMARY
This discussion focuses on filtering noise from an inductive pickup used in a tachometer application. The user is experiencing significant noise interference when measuring signals from the inductive pickup connected to an HT lead on an engine. Recommendations include implementing an active low pass filter, specifically a third-order filter, to clean up the signal. Additionally, it is crucial to identify the source of noise entering the circuit and to ensure proper wiring to minimize interference.
