The Audio Precision Filter Design Package (APFDP) has been produced by Momentum Data Systems, Inc., to allow the user to create DSP filters for downloading to Audio Precision 2700 Series and System Two Cascade analyzers.
The manual below explains the operation of APFDP. It is not intended to be a tutorial on digital signal processing, since there are many excellent texts on the subject, and it is assumed that the user has had a certain amount of academic or professional exposure to the subject.
More advanced versions of this software are available, including versions enabling the design of finite impulse response (FIR) filters. These versions also support more powerful filter design techniques. Please call Momentum Data Systems for further information.
