Construction, theory, and application of non-linear titanate condensers Hobson, John Peter


A method for the making of non linear barium titanate condensers for audio frequencies is described. Preliminary measurements on these condensers are given. An idealized theory for the behaviour of the non linear condensers in a carrier amplifier circuit is developed. A carrier amplifier built on this principle is described. A theoretically possible power amplification for this amplifier of 180 is derived. Experimental results obtained with the carrier amplifier are given. A power amplification of 70 was obtained. Conclusions on the possible applications of non linear condensers are drawn.
