Abstract
An incremental phase shifter for digital signals adapted to combine weighted amount of two quadrature square waves so as to generate a wave having a phase intermediate the respective phases of the two quadrature square wave signals. The generated wave is then processed in a limiting and integrating circuit so as to produce a square wave which is linearly related to the assigned weighted amounts of the two quadrate square waves.
