I became aware of harmonics and the sound of different shaped waveforms early in my electronics career (mid 1970’s) as I was an avid fan of [Emerson Lake and Palmer], [Pink Floyd], [Yes], and the list ...

The circuit in Figure 1 seems utterly simple but demonstrates unusual behavior. It produces an almost square wave of odd-integer quartz harmonics, including its main frequency. You can determine the ...

In LLC Power Conversion Explained, Part 1: Introduction of this series, it was learned that the operation of the LLC requires the creation of a primary side sine wave current that is converter to a ...

Many microcontrollers or PICs will have uncommitted digital-to-analog converter (DAC) outputs that can be used to generate sine waves. But these are generally low resolution (8 to 10 bits), yielding a ...
