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 term orthogonality derives from the study of vectors. Most likely you have run across the term in basic trigonometry or calculus. By definition, two vectors in a plane are orthogonal when they are ...

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 ...
