| A signal amplifying system having an oscillator and an amplifying circuit. The oscillator has a first resistor with a first resistance R1 and a first capacitor with a first capacitance C1, and generates an oscillating signal having a frequency f which equals to k1/(R1*C1), k1 is a first proportional parameter. The amplifying circuit has an input terminal to receive an input signal and amplifies the input signal under the control of the oscillating signal. The amplifying circuit has a second resistor with a second resistance R2 and a second capacitor with a second capacitance C2. The amplifying circuit has a −3 dB bandwidth W−3 dB which equals to k2/(R2*C2), k2 is a second proportional parameter. In this signal amplifying system, the product of the first resistance R1 and the first capacitance C1 is proportional to the product of the second resistance R2 and the second capacitance C2. | ||||||

| 1. A multistage magnetic amplifier having an a.c. line, each stage comprising a pair of closed magnetic circuits and two branch circuits connected across said a.c. line, each branch circuit including in series a reactor winding respectively disposed on one of said magnetic circuits an impedance and two unidirectional devices, said devices in each of the stages being poled in the same direction and the devices in successive stages being respectively oppositely poled, each stage also comprising a control circuit including two control windings, one control winding being disposed on each magnetic circuit, one control winding being arranged to aid the flux induced by the reactor winding of one core and the other control winding being arranged to oppose the flux induced by the reactor winding on the other core, means conductively connecting the control circuit of the stages after the first stage to the branch circuits of the preceding stage at points between the two unidirectional devices in each branch circuit of the said preceding stage, and a single biasing resistor connected in shunt relation to the two unidirectional devices and the control circuit connection in one of said branch circuits.
