FilterDesignLab-IIR for Pc

1. For a given filter brickwall specification of a digital lowpass, highpass, bandpass, or bandstop, it instantaneously finds the optimal Butterworth, Cheby-I, Cheby-II, or Elliptical filter of lowest order.

2. The filter function can be generated for signal postprocessing or for real time applications, where new data is entering the system at a given rate.

3. It is structured into four views for designing the gain, analyzing the phase, simulating test signals, and generating code and filter coefficients.

4. The resulting filter coefficients of the corresponding recursive time domain algorithm are available for further use and accessible by Copy&Paste.

5. The resulting filter algorithm can be realized in a normal form or a second order structure in the direct form 1 or direct form 2.

6. The phase shift, the group delay and phase delay and the location of the poles and zeros of the transfer function are displayed along with the filter gain.

7. The resulting digital filter is instantaneously applied to a test-signal or an imported data set (csv, ascii, txt - format).

8. FilterDesignLab-IIR is a design and simulation environment for digital Infinite Impulse Response (IIR) filters.

9. The test signal resembles either a shifted noisy sine wave, or a step, respectively, delta impulse signal.

10. The raw and the filtered signal are displayed either in the time or in the frequency domain (i.e spectral analysis).

11. The numerical stability of the resulting algorithm is calculated for a DOUBLE-precision implementation.
