In DDS-mode, only a few commands are needed to e.g. generate a sine wave (orange block), accelerate the frequency (blue block) and lower the amplitude ... well as various modulation types ...

In order to perform this harmonic reduction, a pure sine wave must first be applied to the Class-D amplifier ... The output signal was captured and analyzed in Matlab for the amplitude and phase angle ...

Based on zero-current/zero-voltage switching, this new technology achieves multi-megahertz fixed-frequency switching and kilowatt-per-cubic-inch power densities. A ...
