Sprouting some Fuzz. Creating Distortion in an Amplifier

An amplifier Clipping a Sine Wave.

Finally we are back to circuits and not just talking numbers and math! First, we will do a little summary of what we have recently talked about. Any repeating waveform can be derived from a sine wave and one or more harmonics of that sine wave. A harmonic

The Fourier Series — Part 1

A Fundamental and odd harmonics from 3 to 101

Tonight’s post is about adding multiple sine waves to create another waveform. Each of the sine waves is an positive integer (whole number) multiple of the frequency of the base sine wave. These additional frequencies are called harmonics of the the base frequency. The base

A Right Triangle and the Pythagorean Theorem

A Generalized Right Triangle

Tonight’s post is another one on the subject of simple but very very useful mathematics and geometry. The right triangle can seen almost everywhere in the man-made world. Almost everything is build with straight lines usually running horizontally and vertically. Together those would from rectangles, but a rectangle is inherently

Bigger is not always Better – Filter Capacitors for Power Supplies

A filter capacitor to smooth a half-wave rectifier.

This is a rewrite of the previous post. I had two problems with the previous post. First, I miscalculated the Diode resistance by a factor of 10 and second, I did not put the full load on the power-supply. Ripple is going to look a lot
