Equalizers are generally associated with devices designed to reduce or remove group delay variations across a
filter band. However, some equalizers are meant to flatten gain across the operational band of an amplifier,
filter, or complete system.
Higher order filters, with corresponding greater out-of-band attenuation,
exhibit higher levels of group delay variations at the band edges. Group delay variation distorts signals by
varying the time that the spectral components to move from the input to the output of the filter. Square waves,
for instance, contain their highest frequency components at the band edges, so on a filter with a lot of group
delay, the square wave will exit with rounded and otherwise distorted edges. Such distortion can (and will)
negatively affect the bit error rate (BER) of digital communications.

Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each
listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks due to so many companies asking to
be removed because of some issue with Google Statistics. Your best bet is to use a search engine to find company
