  • Abstract
    A zero to 360° phase shift network having less than 1 percent change in amplitude with respect to phase and using two center tapped transformers with RC circuits and amplifiers is described. The same phase shift is realized using integrated circuit operational amplifiers to replace the audio transformers, thus reducing the size and weight.
