SignalLab library is a set of VCL components, based on OpenWire 2.x for fast Digital Signal Processing (DSP) and data visualization. They allow fast complex signal manipulations with zero lines of program code. Includes: SiganlPlayer and SignalLogger Signal and Noise Generators Scope, and Waterfall components LowPass, HiPass, BandPass, BandStop filters FIR, IIR, BiQuad IIR FFT, DFT, DCT, Goertz, Haar, Conjugate, Hilbert, Median filters, Format converters, Signal combining components, arithmetic components, Format converters, Custom integer, float, and complex data filters.
