Abstract: A signal to be produced, which represents a digital data stream, is generated using the currents or voltages from current or voltage sources selected from multiple current or voltage sources. The current or voltage sources whose currents or voltages are used to generate the signal which is to be produced are selected based on the contents of the elements of a shift register whose input connection has the signal which is to be filtered applied to it.

Abstract: A voltage-controlled oscillator for frequency modulation includes an oscillator core with a tunable resonant circuit component which is driven with a control voltage. Furthermore, a modulator component is provided which is driven with a modulation signal for frequency modulation. The modulator component is additionally coupled to the terminal for supplying the control voltage. As a result, a constant modulation deviation can be achieved over the entire tuning range even in the case of oscillators having a large tuning range. The oscillator circuit is particularly suitable for use in transmitting circuits for digital communication.

Abstract: The ON and OFF states of a second device are controlled by a first device through a three-conductor bus. The bus carries data, clock, and enable signals and the second device is in the OFF state when all the signals of the three-conductor bus have an L level. The second device is in the ON state when at least one of the signals has an H level (higher potential than the L level). The enable signal is set to the H level during the data transmission. Otherwise, it carries an L level, while the data or clock signal has an H level. The system obviates an additional housing pin. The operating state information is transmitted relatively rapidly.

Abstract translation: 第二装置的ON和OFF状态由第一装置通过三导体总线控制。 当三线总线的所有信号均为L电平时，总线承载数据，时钟和使能信号，第二个器件处于OFF状态。 当至少一个信号具有H电平（比L电平更高的电位）时，第二装置处于ON状态。 在数据传输期间，使能信号被设置为H电平。 否则，它携带L电平，而数据或时钟信号具有H电平。 该系统避免了额外的外壳销。 操作状态信息相对快速地发送。
