The blind equalization algorithm is “equanimous” and the characteristic of convergence is not influenced by distortion of channel, it is fit for equalizing deep attenuation channel.
It's kinda like the fact so we know we are down the request a equalization, so we'll do clear later when we know the other side, clear the new request rate.
These prevent the occurrence of a certain noise, which normally arises when air blows into tank pressure equalization openings inflight. The effect is similar to blowing over a glass bottle.
