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

Sometimes it really does work out.

A screen shot of my video.

Upgrading the operating system is always taking a chance. It is a lot like jacking up the whole house, replacing the foundation under it and hoping everything works out. I upgraded my Ubuntu from version 12. something to 14.04 and everything was wonderful until I attempted to run

Purposeful Distortion or It is Cool to be Square

The frequency Spectrum of a Sine Wave. (Click on the picture to expand it.)

Distortion is something that is unwanted in music reproduction systems. Those systems used to be advertised as high fidelity and claimed to reliably reproduce the sound files sent to them from phonograph records, audio tapes, etc. I have not heard

Why both Sines and Cosines with the Fourier series?

Phase Shifting.

So far with the Fourier Series we have made some interesting waveforms but what happens in real life? Things are never as clean in real life as on paper. (Except maybe my smudged up papers.) If you think of a perfect square wave with an infinite number of odd harmonics, what would

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
