What is the function of equalizer?

These devices strengthen (boost) or weaken (cut) the energy of specific frequency bands or "frequency ranges". In sound recording and reproduction, equalization is the process commonly used to alter the frequency response of an audio system using linear filters.

Beside this, what is a equalizer for sound?

Equalization, or EQ for short, means boosting or reducing (attenuating) the levels of different frequencies in a signal. The most basic type of equalization familiar to most people is the treble/bass control on home audio equipment. The treble control adjusts high frequencies, the bass control adjusts low frequencies.

What is transversal equalizer?

A transversal equalizer is a transversal filter (or FIR filter) that usually has adjustable weights / coefficients in the filter so that the equalization can be adjusted for best performance. In the latest IEEE Spectrum there is an article by or about Bernie Widrow who pioneered LMS adaptive filters.

What is meant by adaptive equalization?

An adaptive equalizer is an equalizer that automatically adapts to time-varying properties of the communication channel. It is frequently used with coherent modulations such as phase shift keying, mitigating the effects of multipath propagation and Doppler spreading.
