DSPLab is a library of delphi components for digital signal processing. The library contains two components: IIR Filter and FFT. IIR Filter is Butterworth, Bessel and Chebyshev infinite-impulse-response (IIR) filters, with lowpass, highpass, bandpass or bandstop characteristics. You can build the filter of first order, filter of second order, and so on. The maximal order of filter is eight. The FFT component implements Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT).
