PC-DSP - Version 2.0 An interactive, menu-driven digital signal processing package used for discrete-time and continuous-time waveform synthesis using a variety of methods, basic signal operations (arithmetic, nonlinear, and statistical functions), fast Fourier transforms (forward and inverse transforms, window functions), convolution and correlation functions, solutions of difference equations, analysis and design of IIR and FIR filters, digital filter simulation and code generation, power spectrum estimation using classical and modern techniques. Can be extended using the built-in script language. Binary data files generated by PC-DSP are also compatible with PC-SIM.
