DSPLAB for Delphi is a software program that contains a library of Delphi components for use in digital signal processing. This library contains two components, namely IIR Filter and FFT.
IIR Filter, which is Butterworth, Bessel and Chebyshev infinite-impulse-response (IIR) filters with low-pass, high-pass, band-pass or band-stop characteristics which can be built from the filter of the first order, second order and so on.
Eight is the maximum order of filter. The FFT component implements Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT). DSPLAB for Delphi supports Windows 95, Windows CE/Pocket PC, Windows NT, Windows 2000, Windows XP, Windows 98 and Windows ME.
