Abstract

PURPOSE:To enable the usage over a wide frequency range and to obtain phase shift with a wide variety, by using the circuit without frequency dependancy. CONSTITUTION:The output signal (a) in phase with the input signal and the output signal (b) different in the phase by 90 deg. from the input signal are produced from the quadrature signal generator 1. Further, with switches 3b and 3d ON and switches 3a, 3c OFF, the output signals (a) and (b) are respectively fed to the first and the second variable attenuators 4a, 4b. The signals having the amplitudes a1, b1 are output and the signal phase-shifting the input signal by theta1 is obtained by superimposing the two signals at the synthesizer 5. The said amount of phase shift is changeable in the range of 0-90 deg.. Further, with the switches 3a, 3d ON and 3b, 3c OFF, the amount of phase shift theta2 is 90-180 deg., with 3a, 3c ON and 3b, 3d OFF, that theta3 is 180-270 deg., and with 3b, 3c ON and 3a, 3d OFF, that theta4 is 270-360 deg..
