Fpga sine wave inverter

How does the FPGA VI work?

If you run the FPGA VI on a development computer, the Sine Wave Generator Express VI outputs every point of the generated sine wave, regardless of the rate at which LabVIEW calls the VI.

How does an online sine wave generator work?

An online sine wave generator produces a lookup table vector which when plotted (in MATLAB) provides the following sine wave cycle with 256 levels: The above pre-computed sine wave is programmed as an LUT in the source files and a PWM signal is generated whose duty cycle varies with the sine wave''s amplitude:

What if I don''t use the sine wave generator Express VI?

If you do not use the Sine Wave Generator Express VI in an FPGA VI under an FPGA target in the Project Explorer window, LabVIEW uses the default value of 40 MHz for the FPGA clock rate (MHz). Displays a preview of the configured signal power spectrum. The peak corresponding to the configured frequency is normalized to 0 dB.

How do I configure a sine wave generator?

Place a checkmark in the Show frequency terminal checkbox in the Configure Sine Wave Generator dialog box to add this parameter to the VI connector pane on the block diagram. The value you wire to this terminal must be an unsigned fixed-point data type with a 32-bit word length and a 0-bit integer word length.
