Analyzing the Frequency Spectrum of our Distortion Circuits.

The Output Wave Shape of the Diodes in the feedback Circuit.

Now that we have a way of calculating the frequency spectrum of the output from Qucs we can look at the harmonics created by our distortion circuits. The one I was most interested in was the output of the one created by diodes

Sprouting Fuzz part II – Clamping a Signal

A clamp in the feedback circuit.

In the last post we added distortion by simply over-driving an amplifier to the point where it clipped, or squared-off the top of the waveform. It basically said…”that’s all I can do… I can’t do no more”. In this post and video I show two simple op-amp circuits

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
