Abstract: A monodirectional, current-reducing impedance magnifier (MCRIM) provides continuously variable magnification of any general impedance Z.sub.0 without affecting its phase charateristics. The monodirectional, current-reducing impedance magnifier circuit realizes floating resistors, inductors and capacitors, suitable for use over any range of frequencies, and the simulated impedance is continuously user-variable over wide ranges. In another embodiment, a monodirectional, generalized impedance synthesizer (MGIS) permits simulation of user-variable floating impedances whose phase and frequency characteristics are widely subject to design objectives. In addition to realizing all conventional circuit elements R, L and C, including positive and negative values thereof, the MGIS produces an infinite set of alternatives for the simulation of user-variable resistance and reactance functions of frequency. The MGIS is also usable over any bandwidth.
