This is a Toy Scope or a waveform display which i will integrate with my other tutors to display AC points in place of voltmeters. I am not yet sure it will work for that.....?

. feeling it works ok.

Presently you can play with it. Power On and keep pressing the demo button give a few seconds between presses, to see all the waveforms stored. Tweak the four pots all you want, to understand something of this ancient electricity visualization apparatus.

Write an equation similar to the Nine demo waveforms. It has to be Javascript Math only.

This scope "API" has few variables you can use in equation.

xmov	x axis	horizontal value
h_pot	x gain	horizontal gain or Attenuation
v_pot	y gain	vertical gain or Attenuation

The Oscilloscope is a Real Time Graph of Volts Y and Time X at any node of a circuit. It can show both AC and DC.

This is a Virtual JS Oscilloscope - code here - digital-oscilloscope
Fourier Series Periodic Waveforms using JavaScript.

Please Note -

For this Tutorial use a New Chrome Browser and a PC manufactured on or after the year  2004. This tutor uses more Mem and CPU as is creates a Pixel and Vector Trace.
