In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived, geometrically, from a circle (hence why trig functions are also known as “circular” ...

The traditional analog function generator with its customary triple-threat ensemble of square, triangle, and sine waveform outputs is a familiar tool on electronics lab benches. It’s also a classical ...

Swept sine waves are useful when you want to test a product over a wide frequency range. A large research project included the requirement to determine wave propagation in the open ocean. This ...
