A: As frequency increases all amplifier exhibits losses due to internal capacity or internal devices frequency limit. At the hi end of the frequency the amplifiers begins to loose gain gradually as a function of higher frequency that is what roll off is.
A: Any amplifier will reach a frequency cut off point because of hindered circuit capability however the roll of bust be controlled especially when reaching oDB point must be at a -3 db roll off to prevent hi frequency oscillation
The roll off filter removes low frequencies. Usually at about 75 HZ and bellow.
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.

A roll off truck is one that is used to haul roll-off containers. A typical roll-off truck can be bought online from the Benlee website, and can be shipped from Cleveland or Detroit.

A full roll is very sturdy, while a mostly used roll is more fragile. Therefore, when you go to pull the paper off the full roll, it comes off easily without you having to steady the roll...but if you want to tear paper off a mostly used roll, you'll have to hold the roll down before you tear it off so the roll doesn't fall. Basically, because a full roll is sturdier than a mostly used roll.

The roll off in rock and roll dancing is when the lady spins out from a closed position to about a arms length away.

The higher the rate or roll-off, the higher the out of band attenuation.
