Free filter design tool
adds simulator
The FilterExpress 4.0 digital filter design
software has added a simulator called FilterSim
to rapidly develop and evaluate DSP-based filters
of almost any kind–including processor efficient
multi-rate designs. Simulation results can be
viewed graphically and may be analyzed using
standard functions, such as FFTs, or analysis
wizards for common functions such as
signal-to-noise ratio and total harmonic distortion.
The user interface allows direct entry of any
filter specifications using just one screen. The
tool supports both single- and multi-rate designs
including mixed FIR/IIR multi-rate filters.
