Our in-house DSP software tool, called Zardoz™, is a target-language agnostic tool for generating signal processing structures. It can generate a series of different structures such as:

IIR Filter Types
Butterworth (Low pass, High pass, Band pass and Band stop)
Chebyschev type 1 and 2 as above
Oscillators
Resonators
FIR Filter Types
Windowed Filters (Barltett/Blackmann/Hamming/Hann/Kaiser)
Frequency Sampling
Rectangular
User Defined
Rate Changing
Cascaded Integrator/Comb filters
Interpolation and Decimation
Lookup Tables
Sin/Cosine Tables
FSK/MSK modulators
Communications
Raised Cosine
Square Root Raised Cosine
Frequency Analysis
FFT
LMS DFT
Zardoz Capabilities

The graphical interface enables viewing of filter characteristics such as:-

  • Magnitude from Transfer function or FFT of impulse response
  • Impulse response
  • Phase plot
  • S/Z plane pole/zero plot

A sample plot of an IIR filter magnitude response and Z plane plot are shown below.
