ABSTRACT:
A method of phase-shifting an electrical signal (E) of given amplitude and phase angle. The basic function in the method comprises vectorial adding (.SIGMA.) of the two input signals (E1, E2) of the same amplitude but with different phase angles, an operator to correct the amplitude of the vectorial sum (.SIGMA.1), and an operator (C) to select one of the three signals (E1, E2, .SIGMA.1), which have different phase angles. The phase-shifter operates iteratively until the required phase-shift is obtained. All applications, mainly in the microwave range, to radars, telecommunications, etc.
