WebJan 27, 2024 · The state that represents the high pass filter is denoted by η. In the literature, the equation is represented as: d η d t = − ω η + ω y. My question is, which principle did they use to arrive at that equation. I know that the inverse Laplace transform of s s + ω. will result in a differential equation, as it is being multiplied by s. 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.
