In the 1990s, Bose manufactured a "Lifestyle 901" system that integrated two 901 speakers, the 901 Active Equalizer, and a Lifestyle stereo receiver that integrated an A/M-F/M radio tuner and a CD player, as well as a remote control.
For instance, the Bose 901 speaker system does not use separate larger and smaller drivers to cover the bass and treble frequencies. Instead it uses nine drivers all of the same four-inch diameter, more akin to what one would find in a table radio. [citation needed] However, this speaker system is sold with an active equalizer. That equalizer ...
A television equalizer consequently typically requires more filter sections than an audio equalizer. To keep this manageable, television equalizer sections were often combined into a single network using ladder topology to form a Cauer equalizer. The second issue is that phase equalization is essential for an analog television signal.

A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
Bose argued that the listener's perception was the best measure of audio quality. [12] [13] [14] Also in 1968, the company introduced the Bose 901 stereo speaker system, which used eight mid-range drivers pointing toward the wall behind the speaker, and a ninth driver toward the listener. This design aimed to achieve a dominance of reflected ...

This equalizer was able to correct for the losses in various lengths of coaxial cable type BICC T3205 (a commercial high quality 75Ω video cable). The equalizer was a bridged-T circuit, rather than a lattice, as was appropriate for coaxial cable, Two versions of the circuit were produced, one for cable lengths of 0 to 100 feet and the second ...
An adaptive equalizer is an equalizer that automatically adapts to time-varying properties of the communication channel. [1] It is frequently used with coherent modulations such as phase-shift keying, mitigating the effects of multipath propagation and Doppler spreading. Adaptive equalizers are a subclass of adaptive filters.
