    摘要: A sampler (1) samples an inputted base band signal in accordance with a sampling clock, and holds a sample value (S.sub.n). Delay circuits (7, 8) hold sample values (S.sub.n-1, S.sub.n-2), respectively. A decision circuit (2) determines the sample value (S.sub.n-1), and outputs data (d.sub.n-1). A constant multiplier (16) multiplies the data (d.sub.n -1) by a constant (.alpha.). A subtracter (17) subtracts the data (d.sub.n-1) from the sample value (S.sub.n-1). Another subtracter (13) subtracts the sample value (S.sub.n) from the sample value (S.sub.n-2). A multiplier (14) multiplies the output of the subtracter (17) by that of the subtracter (13), and outputs a timing error signal. A low-pass filter (15) extracts a low frequency component of the timing error signal, and supplies a control voltage to a voltage controlled oscillator (6). The voltage controlled oscillator (6) outputs a sampling clock having a frequency which depends on the control voltage.

    摘要: A data frame which is transmitted from a transmitting station is provided with an individual response part (RS) having response bits (S1 to SN) corresponding to all stations on a network, so that the transmitting station initializes the individual response part (RS) in data transfer. Each receiving station outputs its own state to a prescribed position of the individual response part, and the transmitting station monitors the individual response part. Thus, it is possible to correctly confirm whether or not the data is normally transferred to those of the receiving stations which are to receive data.
