Abstract: 発信器に由来する変化する入力信号から少なくとも１つの出力信号を求めるための２チャンネル方法では、２つの互いに独立なチャンネルが形成されている。 入力信号が交替でこれらのチャンネルに供給され、マルチプレクサ（２０）がチャンネル間の切換のために用いられる。 一方のチャンネルにおけるマイクロプロセッサ（１６−１）がテスト入力信号を用意し、テスト入力信号は、変化する入力信号を現在受け取っていないチャンネルに供給される。 これに応じてこのチャンネルは出力信号を出力し、その出力信号は、このチャンネルが正しく動作するかどうかを検査するために予測値と比較される。 同時に他方のチャンネルが出力信号形成のために用いられる。 その後にマルチプレクサ（２０）によって制御信号（２２）に基づいて切換が行なわれる。

Abstract: An evaluation arrangement for a digital incremental transmitter of the type wherein two phase-shifted sinusoidal voltages of the same period are produced generates a periodic triangular voltage signal which is subsequently converted to digital values. The digital values are produced in response to an interlinking of linear portions of the sinusoidal voltages. The digital values are used to address a read-only memory in which are stored a plurality of absolute values within a period.

Abstract: PROBLEM TO BE SOLVED: To provide an input method of an encoder signal capable of surely detecting a signal of an encoder by use of the input period and frequency of the encoder signal to a microcomputer.
SOLUTION: The input method of the encoder signal sets a period of an interruption signal outputted from the microcomputer shorter than an output period of the encoder signal. The input period of the encoder signal to the microcomputer by the operation of the encoder is determined, and control is performed based on the determination of a continuous/discontinuous input. When the encoder signal is continuously inputted, the input frequency is counted, and the sensitivity of the encoder signal is adjusted so that an item of a following state can be selected from an initial state.

Abstract: PROBLEM TO BE SOLVED: To continuously generate, by digital signal processing, noise-suppressed digital phase data representing the phase of an incoming analog signal.
SOLUTION: A method of digitizing first and second signals in imperfect quadrature for obtaining characteristic parameters of the first signal includes a step of providing a first signal 148, which includes an inphase quasi-sinusoidal analog signal. The method includes a step of providing a second signal 142, which includes a quadrature signal. The method includes a step of digitizing the first signal at a sampling rate to generate a first plurality of sets of digital signal waveform samples, and a step of digitizing the second signal at the sampling rate to generate a second plurality of sets of digital signal waveform samples. The method includes a step of digitally processing successive first and second sets of digital signal waveform samples to generate continually updated digital characteristic parameters representing a characteristic behavior of the first signal.

Abstract: An optical code disc includes a fine track which provides a high resolution signal, at least one V scan natural binary track synchronized to the fine track by lead and lag detectors, and Gray code tracks which provide the most significant bits of the digital output of the encoder system. The number of circuit elements in the multiplier circuitry associated with the fine track are reduced by means of a quadrant switching technique whereby the sinusoidal inputs to the multiplier are repeated through each quadrant of the fine track cycle. The V scan and Gray code tracks are optically multiplexed to reduce the number of leads from the optical detector. The use of both V scan and Gray code tracks minimizes the number of detectors required in the system while maintaining large detector signals from each track. The V scan and Gray code outputs are synchronized by the use of an overlapping bit.
