Overview

Signal Processing Resource Center » LabVIEW Signal Processing Shipping Examples » Bandlimited Signal Generation

This VI utilizes the waveform data type. It takes as inputs the type of waveform, number of samples, phase in, and frequency of the waveform to be generated in Hz. This VI is capable of generating large waveforms one block at a time. The block size is determined by the sampling info input. The Multitone Generator subVI remembers phase information between calls to enable a continuous waveform output. Signal parameters can be changed on the fly; hit the Reset button to update the generation parameters.
