Low-Pass Digital Filtering From RapidSTM32

Digital filter is performed by the mathematical operations that can be determined easily its characteristics, especially the sharpness of filter. Even though, infinite impulse response (IIR) digital filter have a sharper transition region and low passband ripple. There is no requirement to use a high-order of IIR digital filters. Therefore, IIR filters require much lower speed processor in practical implementationthan another filters. Furthermore, a common method is to design a high-order digital filter as a cascade series of second-order subsystem, which is making them more stable
