Cannot Delete Files As sudo: Permission Denied. A true differentiator cannot be physically realized, because it has infinite gain at infinite frequency. @CaveJohnson: The correct verb is "differentiate" (as OP demonstrates), not "derive", despite the word "derivative". a 'negative' change. If we now divide by the mass density and define, c2 = T 0 c 2 = T 0 . we arrive at the 1-D wave equation, 2u t2 = c2 2u x2 (2) (2) 2 u t 2 = c 2 2 u x 2. Frequency = 500hz . A passive differentiator is used to "shorten" the pulse width of a square wave by sending the differentiated signal to a "level detector" circuit, which outputs a "high" signal ( 5 volts) whenever the input exceeds 3.5 volts and a "low" signal (0 volts) whenever the input drops below 3.5 volts: The Fourier series for the triangle wave is given by f(x)=8/(pi^2)sum_(n=1,3,5,. Adjust the sensitivity of the scope so ve becomes visible. The key observation is that a sine wave is the same as a cosine wave, but shifted by $\frac \pi 2$ As the triangle wave is odd, the derivative of the square wave is even (plot it) so should be a sum of cosines. Add details and clarify the problem by editing this post. The circuit I have designed features a series resistor (Rin) and capacitor. The single interesting value of the first derivative can be immediately read off from the graph, and does not require differentiating floor and mod functions. Plot the output waveforms.
