Abstract :
The paper covers “Filtration” software developed by author. “Filtration” software allows the design of low-pass filters up to an 8th order filter with Chebychev, Bessel, Elliptic, Hamming, Kaiser, RMS or Butterworth responses from frequencies of 0.1 Hz to 1 MHz. “Filtration” software also can be used to design band-pass and high-pass filters with Chebychev, Bessel, Elliptic, Hamming, Kaiser, RMS or Butterworth responses. Options (specify order of filter, enter the value of signal to noise ratio) are available. Once the filter response has been identified, “Filtration” software generates the frequency response and the parameters of design filter. Software also will recalculate all values to meet the desired response, allowing real values to be substituted or changed as part of the design process. “Filtration” software allows to filtered noise on the base of the data, which corresponds to some measured signal, and to choose the desired type of digital filter, which eliminated unnecessary frequencies (noises) from input signal the best way. Software package was created by using Visual C++ environment.
