High-pass filter. A high-pass filter is shown in Figure 7. The corner frequency is the same as the low-pass filter: 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.

In communication systems, when the IF frequency is quite high, some low-frequency spurs need to be filtered out, such as the half IF spur. To do this, design a band-pass filter. For a band-pass filter, it is not necessary to be symmetrical for low-frequency and high-frequency rejection.
