The bandwidth of a band pass filter is the frequency range that is allowed to pass through with minimal attenuation. Access the main home page, select a location and click “Begin Test” (see Resource section). A low-pass filter (LPF) attenuates content above a cutoff frequency, allowing lower frequencies to pass through the filter. What is a high pass filter used for?Ī high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. This effect can therefore be used to reduce low frequency noise. High-Pass Filter passes frequencies above its cutoff frequency and attenuates frequencies below its cutoff frequency.
