Bridged-tee circuits are widely used as null networks [l]. This paper shows that bridged-tee networks may be devised for phase shifting or phase modulating and gives the necessary relations between circuit constants when the phase displacement is produced by an adjustable resistance, inductance, or capacitance in the proper branch of the tee. Advantages of these circuits will be seen to include: wide-range phase shift without change in attenuation; common ground for input and output circuits, as well as for one end of a single adjustable control impedance; large change in phase with small variation in control reactance; ability to work into a low resistance load; stability; and simplicity.
