Detailed Description

template<uint8_t A = 10>
class EWMA_average< A >

Exponentially Weighted Moving Average.

The smoothing factor is the approximate amount of values taken to calculate the average. Since the Arduino is very slow and does not provide any dedicated math co-processor, the smoothing factor will be rounded to the previous power of 2. Ie 120 will be rounded to 64. This allows to perform all the calculations with integer math, which is much faster !

Note

Because of the 'sign extension', the sign is copied into lower bits.

Template Parameters

A	Smoothing factor
