Abstract: A circuit (1) for synthesizing an impedance associated with a telephone subscriber's circuit (2) connected to a two-wire telephone line (3) is a positive feedback configuration comprising: a single precision resistance (R) connected serially to the line (3); at least one low-pass filter; and an amplifier (7) between the filter (8) and the resistance (R). This circuit (1) allows both the termination impedance and the balance impedance to be synthesized through a single external precision component.
