    摘要: Bottom detection circuit (5) detects the bottom of an RF signal from an addition circuit (3). The output signal of bottom detection circuit (5) is converted into a digital signal with A/D conversion circuit (10) to obtain maximum and minimum values using maximum value detection circuit (12) and minimum value detection circuit (13). The maximum and minimum values are applied to an arithmetic processing circuit (14) and a reference value is calculated based on that minimum value or maximum value. The reference value is held with hold circuit (15) and then converted into an analog signal with D/A conversion circuit (16). During track jumping, the output signal of bottom detection circuit (5) is compared with a reference voltage Vref corresponding to the reference value with comparison circuit (17) to obtain an output signal that corresponds to the presence or absence of a track. In this manner, track detection based on the bottom detection output of an RF signal is not affected by scratches or the like on an optical disc, and accurate track detection is possible. Tracks are detected using the peak detection output when only the peak detection output of the RF signal is unaffected by the presence of scratches or the like on the optical disc.

    摘要: A circuit for performing pre-mastered pit/pre-mastered groove discrimination on an optical disk while an optical pickup traces and traverses tracks. Output signals applied to the input terminal from light receiving elements are summed in an adder circuit and are then applied to first and second transistors. The output signal from the first transistor Is that obtained by envelope detecting the output signal of the adder circuit and is subtracted with the output signal of the second transistor in the subtracter circuit. Then the output signal of the subtracter is compared with a reference value Vref in a comparator circuit. The comparator's output signal according to the result of comparison Is applied to a retrigger monostable multivibrator, which generates an output signal according to the result of pre-mastered pit/pre-mastered groove discrimination. Thus a pre-mastered pit/pre-mastered groove discrimination can be performed with accuracy even while the light pickup traverses pre-mastered pits and pre-mastered grooves.

    摘要: In a delay circuit for inputting square waves, fluctuations in the amount of delay brought about by noise pulses present in input signals are reduced. A switch (SW3) is controlled by an output signal (Vdo) from a Schmitt comparator, and selects either an electric current source for supplying a charging current to a capacitor (Cst) or an electric current source for supplying a discharging current. A current supply from the selected electric current source is turned on/off by controlling switches (SW1, SW2) using an input signal (Vdi). The Schmitt comparator switches the level of Vdo in accordance with a voltage of Cst. The charging current is supplied to Cst when Vdi is H level at rising edge of Vdi, and the discharging current is supplied to Cst when Vdi is L level at trailing edge of Vdi.

    摘要: An upper end voltage and a lower end voltage of a current detection resistor Rs are supplied, via first and second switches S1 and S2, to one end of a main capacitor Ci. A reference voltage VREF is supplied, via a third switch S3, to the other end of the main capacitor Ci. The operational amplifier OP has a negative input terminal to which a voltage of the other end of the main capacitor Ci is supplied and a positive input terminal to which the reference voltage VREF is supplied. The circuit performs an operation for charging the main capacitor Ci with a voltage corresponding to a difference between the lower end voltage and the reference voltage in a state where the first and third switches S1 and S3 are turned on and the second switch S2 is turned off. The circuit obtains a voltage applied to the other end of the main capacitor Ci which is equivalent to a sum of the reference voltage VREF and a difference between the upper end voltage and the lower end voltage in a state where the first and third switches S1 and S3 are turned off and the second switch S2 is turned on. The circuit detects a voltage difference between two ends of the current detection resistor Rs based on a value obtained by the operational amplifier OP that subtracts the reference voltage VREF from the obtained voltage.

An oscillator outputs a mixing signal having a frequency difference of at least a barely audible frequency within an audio frequency band from any broadcast station center frequency allocated at a predetermined frequency spacing, the mixing signal is mixed with the signal received by the antenna, and the IF signal is obtained.
