Ignition Switch Voltage Filter Coefficient

A filter can be applied to the voltage from the ignition switch. This is useful for smoothing a noisy signal and reducing the intensity (or amplitude) of sudden spikes and dips in the signal.

The number is a decimal between 0 and 1, which specifies the strength of the filter. Values near 1 would not filter out much (weak filtering). Values near 0 would filter out the whole signal (very strong filtering).

• 1 = output an unfiltered signal. That is, output signal is equal to input signal.
• 0 = output null signal. Not recommended.
