Title: Active filter circuit
Inventor: YAMAMOTO TAKESHI
IPC: H03H11/12
Filed: 1988-11-18
Abstract: PURPOSE:To improve an S/N and to reduce a capacity so as to make the title circuit into IC by feeding back the output of an integrating circuit provided in a final stage to an input terminal through the use of more than a pair of a transformer conductance amplifier and an integrating circuit provided on the output-side of the amplifier. CONSTITUTION:The integrating circuit consisting of an operational amplifier OP1 (OP2), resistances R1 and R2 (R3 and R4) and a capacitor C1 (C2) causes a current obtained by increasing a current flowing in the capacitor C1 (C2) by the rate of the resistances R1 and R2 (R3 and R4) to flow to the output-side of the optional amplifier. Consequently, an effect as a capacity increase circuit which has equivalently increased the capacity is given. In the equivalent circuit, a capacity value viewed from a terminal P0 shows a value that a capacitor CA has been multiplied by (RA+RB)/RA. When the rate of the resistances RA and RB is selected to be large, the capacitor of the large capacity can be equivalently realized by the capacitor of the small capacity. Consequently, the S/N can be improved without increasing the capacity value.

Abstract: PURPOSE:To attain stability of a gain at an oscillation limit point by feeding back a control loop control signal to a control means so as to control the gain of the control loop at the oscillation limit. CONSTITUTION:The output of a differential amplifier 12 corresponds to the error 20 of a directly coupled feedback system, the value is in general 1/1+G object value 21 and it is possible to detect the characteristic of the control loop. Further, in a closed loop, the frequency causing the oscillation of the loop depending on the phase and gain such as a Baud diagram is fixed nearly. Thus, a loop characteristic detector 16 is provided to the output of the differential amplifier 12, the reference level 18 and the output of the loop characteristic detector 16 are compared by a level comparator 17 and the control loop is fixed at the oscillation limit point by applying increase/decrease control to the gain of a VCA 19 so as to bring the output into the reference level 18. Thus, the control loop is controlled at the oscillation limit.

Abstract: PURPOSE:To measure the positions of plural targets which are present on a concentric sphere having its center at a transmitter-receiver by using >=2 transponders which respond to a sent signal from the transducer at different frequencies. CONSTITUTION:The pulse-modulated signal of frequency f0 generated by a transmitter 1 is sent to the transducer 3 through a transmission/reception switching circuit 2 and converted into an ultrasonic wave, which is radiated into water. This ultrasonic wave signal is received by the transponders 4 and 5 installed underwater.
