ABSTRACT:
An improved signal isolator including two nonlinear circuits having nonlinear voltage-to-current characteristics, in which an input network is formed by connecting one of the nonlinear circuits in series with the primary winding of a transformer, and an output network is formed by connecting the other nonlinear circuit and an averaging circuit in series with the secondary winding of the transformer. A pulse signal is applied to the input network, the output network or the tertiary winding of the transformer to develop an output signal corresponding to the input signal while the input network and the output network are isolated from each other with respect to direct current.
