Characteristics of Analog Equalizer

 

In operation, an equalizer should affect only the desired frequencies and no others in theory. It should be able to process the unaffected signals without altering their characteristics. In reality, however, all analog equalizers distort the signal to some extent. This is because the type of circuitry used to make equalizers (resonant RLC circuits) has some inherent phase distortion (time delay) associated with it. Whenever you put a signal through an equalizer, you will be changing it, regardless of whether you intend to or not. The exact nature and degree of this change (distortion) will vary depending on how much equalizer gain you are using. The more aggressively you equalize a signal, the more phase distortion it will have. At small amounts of equalizer gain however, there is little or no phase distortion. Therefore, when you work with an analog equalizer the moral here is: Use equalization in moderation.
