Our in-house DSP software tool, called Zardoz™, is a target-language agnostic tool for generating signal processing structures, primarily in Verilog, but can be used with any language.
| 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 FIR Filters with Interpolation and Decimation |
| Communications |
| Raised Cosine Pre/De-emphasis filters Sin/Cos Modulators CTCSS Encoder Goertzel Tone Decoder |
| Adaptive Filter |
| Least Mean Square (LMS) LMS DFT Minimum mean squared error (MMSE) |
| Frequency Analysis |
| FFT: forward/inverse, Decimation in Time/Frequency |
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.
