WebWith the high-pass filter, increasing the frequency will slightly raise the output, while decreasing the frequency will drastically decrease the output. The low-pass will experience an output drop upon increasing the frequency, and a slight increase in output if the frequency is decreased. The goal of this stage can be seen in Figure 8 below. WebA filter is a circuit whose transfer function, that is the ratio of its output to its input, depends upon frequency. There are three broad categories of filter which are widely used: Low-pass filters allow any input at a frequency below a characteristic frequency to pass to its output unattenuated or even amplified.
