Abstract: A synchronization equipment performs correlation processing between a first known pattern included in a received signal and a second known pattern, and detects reception timing of the received signal. A correlation value computing portion computes a correlation value between the first known pattern and the second known pattern at every reception time. A reception timing detection portion compares the computed related value with a predetermined threshold value, determines the reception time when the correlation value becomes larger than the threshold value to be the reception timing of a received signal, and, after this determination, suspends the comparison between the correlation value and the threshold value, and holds the reception time determined to be the reception timing.

Abstract: An equalizer block forming part of a receiver compensates transmission path characteristics of a baseband received signal to generate a prediction signal, and differential-logic-converts a demodulated signal generated by demodulating the prediction signal to generate a differential-logic-conversion demodulated signal. A differential-detection demodulator block differential-detects the prediction signal from the equalizer block and subsequently demodulates the differential-detected prediction signal to generate a differential-detection demodulated signal. A selector block selects either the differential-logic-conversion demodulated signal from the equalizer block or the differential-detection demodulated signal from the difference-detection demodulator block.

Abstract: In a graph displaying method and apparatus and a processing operation monitoring apparatus, a succession of graph points representing the progress of a process are sequentially displayed from one side to the other on the graph display area of a screen, one added at a time to the leading end of the graph. When the latest graph point arrives at the right end of the graph display area, the graph is shifted back leftwardly to a predetermined position at a speed that can be followed by the operator's eyes, whereupon an additional succession of graph points are sequentially displayed at the leading end of the graph. While the graph is being shifted from the right end of the graph display area to the predetermined position, a plurality of transient graphs is successively displayed from the start position of the movement to the terminating position, thus maintaining continuity of the displaying graph so that the operator can monitor the progress of the process without interruption and/or misrecognition.
