Detailed Description

template<typename T = short> template class pp::Filters::LowPassIIR

Low Pass Infinite Response Filter functor for use with STL algorithms.

The basic equation is: y[n] = (0.5 * x[n]) + (0.5 * y[n-1]) where x is the input and y is the output.

This filter outputs the average of the current sample input and the last sample outputed.

H(f) = c1 /(1 - c2*z) where z = e^(-2*PI*i*deltaFrequency) real H(f) = c1/(1-c2*cos(-2*PI*deltaFrequency))
