WebDepending on the configuration of the components you can construct a low pass or high pass filter. The low-pass filter will pass a signal with minimal distortion up to the cutoff frequency, at which point it will block the input signal. The high-pass filter will block the frequencies below the cutoff frequency and pass the ones above. WebThe major difference between high pass and low pass filter is the range of frequency which they pass. If we talk about high pass filter, so it is a circuit which allows the high frequency to pass through it while it will block low frequencies.
