WebHigh Pass Filter. High pass filter as the name suggests, it allows (passes) only high frequency components. That means, it rejects (blocks) all low frequency components. The s-domain circuit diagram (network) of High pass filter is shown in the following figure. It consists of two passive elements capacitor and resistor, which are connected in ... WebNov 29, 2024 · When you cut out frequencies from one group, you help another shine or become more heard. Therefore, a high pass filter can be used as a way to promote higher frequencies in your mix. This is especially great for a vocal track where more of the high end can help create a brighter, crisper sound with more clarity. 3.
