For smoothing up to 4 digital/PWM signals to a stable analogue voltage.
Resistor and capacitor values will need tuning depending on expected PWM frequency and voltage so please provide details when ordering.
For example PWM (DPO pulsed) output from Haltech ECU at 2.2khz, 12 volts, to be sent to a Smiths analogue gauge expecting constant voltage ranging from 0-12v. 50% PWM duty cycle would provide a stable 6 volts to the gauge.
