摘要： A synthesized oscillation circuit that can relax a limitation of the maximum operational frequency. A mixer (MX), a bandpass filter (BPF), an amplitude limiting amplifier (LIM), a phase detector (PD), a low-pass filter (LPF), and a voltage-controlled oscillator (VCO) are serially connected between a signal input terminal (IN) and a signal output terminal (OUT). The signal output terminal (OUT) is connected the mixer (MX) and the phase detector (PD). The bandpass filter (BPF) has a filtering characteristic which blocks the sum frequency component of the frequency component of an input signal from the signal input terminal (IN) to the mixer (MX) and the frequency component of an output signal from the voltage-controlled oscillator (VCO) to the mixer (MX), but which passes the difference frequency component between them. The low-pass filter (LPF) has a filtering characteristic which blocks the sum frequency component of the frequency component of a signal from the voltage-controlled oscillator (VCO) to the phase detector (PD) and the frequency component of a signal from the voltage-controlled oscillator (VCO) to the phase detector (PD), but which passes the difference frequency signal between them.

摘要： A system for controlling air-fuel ratio for an internal combustion engine having a two-barrel carburetor. An electronic controller compares the output signal of an O.sub.2 sensor with a reference corresponding to stoichiometry and for operating on-off electromagnetic valve(s) for controlling the air-fuel ratio to a value approximately equal to the stoichiometric air-fuel ratio. A constant signal generating circuit is selectively connected to the electronic controller. An engine operation detector is provided for detecting the transition from a heavy load condition to light load condition for producing a signal. A switching circuit operatively connects the constant signal generating circuit to the electronic controller for providing a fixed duty ratio of the valve, and renders the electronic controller non-responsive to the output of the O.sub.2 sensor. A switch actuating circuit is provided to actuate the switch by the output signal of the engine operation detector for a predetermined period. Thus, the on-off electromagnetic valve is operated at a small duty ratio after the heavy load condition for a predetermined period.

摘要： In a frequency-dividing circuit for producing an output having a frequency half that of its input, a pair of terminals of a latch circuit are connected to input terminals of a pair of amplify/delay means, and are also connected to receive through a pair of transistors, the outputs of the amplify/delay means. A single-phase input signal is input to the control electrodes of the transistors to turn on and off the transistors. When the transistors are turned from off to on, the output states of the amplify/delay means are transferred through the transistors to invert the latch circuit, and the states of complementary terminals of the latch circuits are in turn transferred through the amplify/delay means to invert the output states of the outputs of the amplify/delay means. When the transistors are turned from on to off, no change occurs in the states of the circuit. In this way, the states of the circuit are inverted each time the transistors are turned from off to on. A frequency-divided output can therefore be derived at one of the outputs of the first and second amplify/delay means. Either one or both of the first and second inverters may be replaced by a NAND gate or a NOR gate for permitting reset of the circuit.
