The device which does the conversion of a quantity that has continuous changes (usually of voltage) into numbers that approximate those changes.
Comb Filter
1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at short delays.
2) Loosely used to also describe effects that can be achieved with comb filtering as part of the processing.
Crossover
1) A route leading from one side of the stage to the other, out of the audiences view.
2) An electronic filter in a sound system that routes sound of the correct frequency to the correct part of the speaker system. Different speakers handle high frequencies (tweeters) and low frequencies (woofers). Sometimes known as a crossover network. An active crossover splits the signal from the mixing desk into high, mid and low frequencies which are then sent to three separate amplifiers.
3) An electrical circuit that divides a full bandwidth signal into the desired frequency bands for the loudspeaker components.
