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.
