Detailed Description

template<class T1, class T2, class T3>
class itpp::MA_Filter< T1, T2, T3 >

Moving Average Filter Base Class.

This class implements a moving average (MA) filter according to

where b is the filter coefficients, x is the input and y is the output.

When filtering a vector, the length of the output vector equals the length of the input vector. Internal states are kept in a filter memory. The first time the filter is used the internal states have been set to zero.

The class is templated as follows:

• T1 is the type of the input samples
• T2 is the type of the filter coefficients
• T3 is the type of the output samples
