 Finite Impulse Response filters: Finite Impulse Response filters:
 Have a set time duration of response.  FIR filters do not have a feedback loop and feature a constant group delay.  This means that an input signal will have a uniformly delayed output and will have no distortion.  FIR filters are defined by:  Have a set time duration of response.  FIR filters do not have a feedback loop and feature a constant group delay.  This means that an input signal will have a uniformly delayed output and will have no distortion.  FIR filters are defined by:

 FIR Filter-Window is the simplest method of constructing a FIR filter.  Filters are created by scaling a sinc function.  It begins with a perfect passband filter and is constructed with filter coefficients to generate a desired frequency response. FIR Filter-Window is the simplest method of constructing a FIR filter.  Filters are created by scaling a sinc function.  It begins with a perfect passband filter and is constructed with filter coefficients to generate a desired frequency response.

 There is no set method of creation for IIR filters.  In PA the user defines the decimation filter, filter type, filter order, analog prototype, and cutoff frequencies.   There is no set method of creation for IIR filters.  In PA the user defines the decimation filter, filter type, filter order, analog prototype, and cutoff frequencies.  
 Filter_RMS closely resembles the output of 1/N octave filters but with greater flexibility.  Users can design any filter and examine the RMS.  Functionally the same as computing the RMS after applying an RMS filter. Filter_RMS closely resembles the output of 1/N octave filters but with greater flexibility.  Users can design any filter and examine the RMS.  Functionally the same as computing the RMS after applying an RMS filter.
