    摘要: An error propagation detection method and apparatus for use in decision feedback equalization type detection is disclosed, with which it is possible to detect error propagation even when a specific code conversion rule is satisfied in an MDFE system. If the input signal of a comparative decider be a binary signal a(k) expressed as ±1, an error signal ev(k) expressed by ev(k)=[y(k)−Ideal y(k)] sign[a(k)] is determined using a(k−1)≠a(k+1) as an error computation condition. The error signal ev(k) thus determined is checked to see whether it exceeds a specific value. If so, the slice level of the comparative decider is controlled to a corresponding offset value.

    摘要: A signal reproducing circuit for a magneto-resistive effect head includes a constant current source for supplying a sense current to an MR head in a read state, first constant current sources for supplying first constant currents to a pair of reproduction transistors in the read state, and a capacitor connected between the emitters of the transistors. Furthermore, second constant current sources for supplying second constant currents are connected in parallel with the first constant current sources. Control is given so that when switching an idle state to the read state is commanded, the second constant current sources remain on for a given period of time. Owing to this circuitry, a transient period during which the idle state is switched to the read state or a transient period during which heads are switched in the read state can be shortened to a great extent. Consequently, superposition of an unwanted offset component on a reproduced signal can be suppressed, and a loss in data-handling capacity can be minimized.

    摘要: A terminal device capable of preparing a document and communicating data includes a system control section having storage means in which are resident a control program for outputting received document data either to an output section or an external storage, and a supervisor program for alternately practicing the control program and another program necessary for system control. Based on these resident programs, the system control is practiced to permit received document data to be fed to the output section or the external storage even when local work such as preparation of a document is under way. When printing operation is disabled due to a failure in a printer of the output section or the like after the received document data has been loaded in a memory of the communication control, the document data is immediately delivered to the external storage to open the document data storage area. Power is supplied only to the equipments which are indispensable for storing received document data in the memory, except for the duration of any local work such as preparation of document data.
