Abstract
The dielectric constant of certain ceramics, notably the barium titanate family, is a function of the electric field across them. A capacitor employing such a dielectric was incorporated in the tunel circuit of an oscillator. The frequency of oscillation was varied by applying an appropriate steady bias to the non-linear capacitor. By pulsing the biased capacitor with a low frequency square wave, a signal suitable for use in frequency shift keyed radio teletype systems of communications was obtained.
