PURPOSE:To make it possible to transmit data and a word sink (WSD) signal via one transmission line by using the word sink (WSD) signal in different format from the data in a digital signal series transmitting method. CONSTITUTION:Period Tws of WSD signal A is equally divided by thirty two to obtain a digital signal of 32 bits for one word and the unit time of one bit is denoted as T. Then, 20 bits from the 1st bit MSB to 20th bit are used for sampling data, and 12 bits from the 21st bit to the 32nd bit are used as control bits and user's bits. Three bits, the 30th, 31st and 32nd bits, are used for a WSD signal and bits from MSB to the 29th bit are used for an NRZ signal of T in unit time; and the WSD signal is made into the unit time 1.5T NRZ signal to change both the signals in format and while the signal for 32 bits is transmitted in series via one transmission line to a receiver, a word sink extracting circuit in the receiver extracts the WSD signal, so that data bits in one word will be read on the basis of this WSD signal. |
