1 Description

This subsystem demonstrates how the internal ADC, and math accelerator (MATHACL) modules within the MSPM0G family of devices can be used to implement a simple, streaming IIR filter of an analog signal. In this configuration, noise on an analog signal is filtered using a single pole IIR filter. The defined beta value can be adjusted to control the IIR filter decay over frequency.
