摘要： A circuit for obtaining accurate timing information from a received signal, first, obtains an impulse response at a certain phase, which phase is determined based on a reference phase of a receiver clock, and then the obtained impulse response is compared with a reference level. As the reference level: a predetermined value just below the maximum value of the overall impulse response; an impulse response at another phase; or an impulse response at the same phase in a previous period, is used. The reference phase is controlled, according to the result of the comparison.

摘要： A digital transmission system comprising at least two transmitting-receiving (T/R) units and a single transmission line connected therebetween. One of the T/R units the first transmits a control signal to the other T/R units with which frame synchronization and timing recovery are carried out using the transmitted control signal. At the same time, the other T/R unit inhibits transmission of send signal therefrom to the first T/R unit. Further, the send signal from one T/R unit to the other T/R unit is transmitted in the form of a frame. Each frame includes, at its end portion, a non-signal duration portion.

摘要： A data processing system for reading or writing data comprises a data memory unit and a processing unit, the data to be read from or written to the data memory unit is being serially transferred bit by bit over a single line connected between the data memory unit and the processing unit. The processing unit is operated in accordance with an instruction specified by instruction addressing information which is produced by an instruction counter. The data is specified by data addressing information which is produced by a means for specifying the address of the data memory unit. Both the lower bits of the data addressing information and the lower bits of the instruction addressing information are jointly produced by the lower bit stages of the instruction counter. The upper bits of the data addressing information are momentarily stored in an upper bits specifying register during one read or write operation while one execution of one data bit data is performed. Further, the data addressing information is provided synchronously with the provision of the instruction addressinginformation. The number of bits of the data word must be equal to or must be a multiple of the number of bits of the instruction word, or the number of bits of the instruction word must be a multiple of the number of bits of the data word.

摘要： A differential coding circuit including a subtracter, a quantizer for quantizing a differential signal from the subtracter, and a predicted signal generating circuit for generating a predicted signal on the basis of a quantized differential signal from the quantizer. The subtracter subtracts the quantized differential signal of the quantizer and the predicted signal from the sampled input signal. The critical path of the circuit is shortened, therefore the operation speed of the differential coding circuit increases.

摘要： An asynchronous transmission system for binary-coded information is disclosed. According to this system, in a transmitting terminal (A), when successive data of the same code in a set of asynchronous data lasts for a predetermined period of time (T.sub.1), a refresh pulse, the polarity of which is opposite to that of the successive data, is added to a transmission signal. However, the addition of such a refresh pulse to the transmission signal is inhibited for a predetermined period of time (T.sub.2) to allow for a change of data. In a receiving terminal (B), a pulse, the width of which is larger or equal to a minimum period of data, and a pulse, the width of which is smaller than or equal to a pulse-width (T.sub.0) of a refresh pulse, can be discriminated and removed by a pulse-width discrimination circuit. As a result, the refresh pulse is not present in the output signal of the pulse-width discrimination circuit. Thus, the original asynchronous data is restored.

摘要： An apparatus for band compression processing of a picture signal which generates forecasting error signal and movement vector and updates only the movement vector during a comb-out operation. During comb-out processing, a picture signal is recirculated while the movement vector is produced and accumulated. At the end of the comb-out processing, the change in the movement vector from the accumulated vector is within a desired range. Therefore, the scale of a circuit for detecting the movement vector after the comb-out operation does not increase.
