The exact frequency response of the filter depends on the filter design.The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. A low-pass filter is the …

WebJan 30, 2024 · A low pass filter should have a relatively large value for ( 1) and a very small value (ideally zero) for ( 2). For a high pass filter the opposite is the case. If both values are small (and if h [ n] is not zero) then it's probably a band pass filter, and if both values are relatively large, it's probably a band stop filter. WebJan 20, 2024 · In this set of equations, the pole of the initial low pass filter is: and the frequencies are denoted using F. For the high pass filter, any zeros are denoted using ⍵.
