SimDSP is a simulation software that provides a set of functions to implement different digital-signal-processing algorithms. This tool allows to simulate two basic signal processing approaches: sample-by-sample and block-oriented. It also provides functions to control the sampling frequency, displaying data at different formats, keyboard reading and keyboard interruption. SimDSP simulates a data acquisition card with a single input and output.
