摘要： A device has a first operational state for writing information onto a record carrier and a second operational state for reading information from a record carrier. The device includes a phase-locked loop for generating a clock signal from a reference signal and a control unit for generating a pulsed transducer control signal in response to an information signal and the clock signal. The device also includes a generating transducer for generating physically detectable patterns in the record carrier in response to the transducer control signal and a read transducer for generating a read signal in response to physically detectable patterns in the record carrier in the second operational state that includes a radiation source. The device further includes a power supply which supplies the radiation source with an electric power. The phase-locked loop includes a memory for memorizing, in the first operational state, a memory value which is a measure of the supplied clock signal. In the second operational state, the phase-locked loop generates the clock signal in response to the memorized memory value and causes a high-frequency modulation in the electric power supplied by the power supply.

摘要： Sigma-delta modulator in which the gain stage (20) of the input network and the gain stage (22) of the feedback network are regularly interchanged (“chopped”). This averages out the difference between the two gain stages, thus defining the gain of the system accurately. The difference in gain between the two gain stages is modulated on the chopping frequency, which may be outside the frequency band of interest. Furthermore, by using fully differential circuitry the chopping can be effected in such a manner that the offset and flicker noise of the two gain stages are modulated to the chopping frequency.

摘要： An arrangement for supplying energy to a load having a low-pass frequency characteristic. A binary signal having a low-frequency component and a strong high-frequency component having a predetermined frequency is applied to a rejection filter adjusted to suppress the predetermined frequency. The rejection filter is of a type producing a ternary output signal.The load is supplied by means of a control circuit in such a way that, in response to the signal level at the output of the rejection filter, the load is supplied with a positive polarity, with a negative polarity, or the energy supply to the load is interrupted. In this manner a ternary energy supply is obtained having low power dissipation in the control circuit and in the load.

The first differential amplifier receives an operating current from a current source. A second differential amplifier receives an operating current from a current source, and has an input connected to a common signal terminal. A conversion circuit connects the first differential amplifier and second differential amplifier outputs. An output amplifier is connected to the conversion circuit output for amplifying a single ended output of the conversion circuit. A signal from the output amplifier is suppressed by switching the operating current of said first differential amplifier and said output amplifier off, while simultaneously switching the operating current of the second differential amplifier on.
