Hello,

My colleage told me about a smoothing/lpf formula which is :

a(n) =3D {a(n-1) * param + ADC} / {param + 1}

which=20
ADC is the signal from adc
a(n-1)=A0 is the result of the last call to this formula
the param is the part I don't understand.

Is there anybody knows where this formula comes from ?

it seems to work well for smoothing, but I want to tweek the param ( which =
is certainly for the bandwith )

Thank you
