Web22 de mai. de 2024 · Actually, equalizers are a class of adjustable filters that may produce gain as well as attenuation. Perhaps the most common uses for equalizers are in the audio, music, and communications areas. As the name suggests, equalizers are used to adjust or balance the input frequency spectrum. Equalizers range from complex 1/3 octave and … 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 ...
