WebIf the gain goes to zero at both extremes, you have a band-pass filter. If the gain is the same at both extremes, you have a band-reject filter. If the gain only goes to zero at one extreme, you have either a low-pass or a high-pass filter. Of course, there are other possible filters to consider such as, e.g., shelving filters and all-pass ...
