TRANSISTOR RECORDING CIRCUIT WITH COMMUTATOR

摘要

An electronic multiplier for producing an algebraic product comprising means for selectively recording a series of positive dipoles and negative dipoles with blank zones on a mobile information memory track and a corresponding series of either positive or negative dipoles on a mobile reference memory track and means for simultaneously reading and converting to electrical signals successive dipoles (or zones) on the information track and successive dipoles on the reference track and for effecting the product of said signals, wherein the recording on the information memory track is effected by apparatus including a transistorized comparer connected with a transistorized commutator.
