Autoregressive Moving Average (ARMA) Filter Base Class.
This class implements a autoregressive moving average (ARMA) filter according to
.
where a and b are 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 Generated on Sat Jul 6 2013 10:54:34 for IT++ by Doxygen 1.8.2
