According to textbooks, a sine wave is a wave whose form resembles a sine curve. Often in power electronics, we need a sine wave generator for some applications; a dc/ac power inverter, for example.

Med Dyer, Jabra Corp, San Diego, CAGenerating a square wave at a particular frequency is fairly simple. Many techniques for doing so exist, using counters, flip-flops, and–everyone's favorite–the ...

[153Armstrong] did a short post on how easy it is to generate waveforms using Python. We agree it is simple, but actually, it isn’t so much Python per se, it is some pretty cool libraries (SciPy, in ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from many designs. However, designers can use simple high-frequency CMOS ...

The seismic signals from volcanoes are complex waves that result from multiple single waves that occur simultaneously. To help students understand how a complex wave is formed, tell them that in this ...
