# Sawtooth wave python

Does electrical sawtooth wave actually produce sinusoidal oscillations at harmonic frequencies? According to Fourier's theorem, we know that a sawtooth wave can be represented as a sum of sine waves. These sine waves we know as harmonics (in the context of sound). A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the function sine, of which it is the graph. It occurs often in both pure and applied mathematics, as well as physics, engineering, signal processing and many other fields. On The Mathematics of the Sine Wave y(x) = A*(2πft + ø) Why the understanding the sine wave is important for computer musicians. The sine wave is mathematically a very simple curve and a very simple graph, and thus is computationally easy to generate using any form of computing, from the era of punch cards to the current era of microprocessors. triangle oscillator, The circuit is a triangle waveform generator that uses as few parts as possible. A 555 timer IC, 2 resistors and two capacitors make the triangle wave. The IC is connected in a 50% duty-cycle astable square-wave oscillator circuit. The square-wave output is fed from pin 3 of the IC to an RC shaping circuit.

I tried to search for 'scipy triangle wave', and I found a post on stack exchange that reveals how to do a triangle wave with the sawtooth function. It accepts a second parameter that determines the shape of the sawtooth. 1 (the default) gives you a right-sided sawtooth, 0 gives a left-sided one, and 0.5 gives a triangle.
The weak signal is similar to the strong except it plateaus at around 1-2% of the dynamic range except for a few strong peaks poking out. Integration times in the tens of microseconds range I begin to get good signals but the intensity varies like a sawtooth wave.
