12 It can be run on any board supported in Zephyr, but note that CMSIS-DSP is specifically optimized
13 for ARM Cortex-A and Cortex-M processors.
15 A **moving average** filter is a common method used for smoothing noisy data. It can be implemented
16 as a finite impulse response (FIR) filter where the filter coefficients are all equal to 1/N, where
19 The sample uses a very simple input signal of 32 samples, and computes the moving average using a
