Alternative approach

In some cases the filtering using the RC might not be effective. Instead of using costly active

external analogue filters, an internal digital filtering can be implemented using the

decimation filter. The approach is the following:

Choose a simple RC outside filter which cut-off frequency is much higher than the

interested bandwidth of the signal, including the noise.

Oversample the signal, potentially sampling at the maximum frequency allowed by the

ADC

Filter the noise out using the IIR / FIR feature

Decimate

For example this approach can be very effective to threat knock sensors outputs, in which

the big noise cannot be easily filtered out using a simple RC.
