An all-pass phase-shift circuit having an input circuit for supplying signals with reversed phases at first and second terminals, and a phase-shifter bridge circuit with a first capacitor connected in series with a first resistor between the first and second terminals, a second resistor connected in series between the first capacitor and the first resistor, a series connection of a third resistor and a second capacitor connected in parallel with the first resistor, a third capacitor and means for connecting the third capacitor in parallel with the second resistor. A signal applied to the input circuit of the phase-shift circuit is linearly phase-shifted with respect to frequency. |
