High pass filter differential equation
WebMay 4, 2015 · $\begingroup$ Could it be that if the problem assumes that the circuit is not initially powered my solution would be correct? Or other condition like that. The assignment supposes we come up with an equation in the time domain, since we're asked to use fourier transformations later on to join them all together, and use the antitransform to come up … WebElectrical – High pass filter oscillating For equal value capacitors (which you very nearly have) the Q is: - Q = \$\dfrac {1} {2}\sqrt {\dfrac {1Mohm} {20kohm}}\$. By my calculations that is a Q of 3.53 and just a little too high for the sallen key topology given that you have also got gain in the pass band. It will oscillate. Related Topic

WebHence, we have the name high-pass filter. As the input frequency decreases, the reactance XC becomes larger, causing the input to be increasingly attenuated. At the zero frequency, XC will be infinitely high and therefore the output voltage Vout = 0. To analyze the circuit mathematically, we would use the voltage-divider relationship and write.
