File Information

See how it works here:

Run waveform_generator.m

This is second more advanced and more accurate programmed of my Waveform Generator GUI.

The Waveform generator can generate periodic signal of arbitrary shape. Markers used. This also display Fourier series a and b coefficients. It is possible to plot harmonics and save to m-file. It is possible to listens sound. There are 10 presets for classic waveforms.

Continuous play option can be used only if DAQ toolbox installed. If continuous play stop because of markers move then increase buffer size: bufferSize, nblocks, margin variables in gui opening function. Generate m-file means generate m-function using current settings, the function is waveform as function y=function_name(x), that is periodic.

The generator used intractive_curve class.


Waveform Generator Gui and Interactive Curve Class inspired this file.

Required Products Data Acquisition Toolbox
MATLAB release MATLAB 7.10 (R2010a)
Other requirements The Data Acquisition Toolbox need only for continuous play option.

Does the utility have real-time AM and sweep inputs (FM)?

In other words, does Matlab use the sound input capabilities of the sound card too.

update No. 1: add option "redraw harmonics", now it is possible to turn off harmonics for speed.
