Abstract

PURPOSE:To increase number of transmitted items, by superimposing other data consisting of shorter pulses on a data signal. CONSTITUTION:The 1st data signal is transmitted through parallel-serial conversion. In this case, a synchronizing signal (b) is given to a pulse oscillation circuit 12 and a pulse pickup circuit 13. The circuit 12 generates a pulse with shorter period in synchronizing with the synchronizing signal (b). The circuit 13 is operated as a gate to the said pulse based on the 2nd data signal inputted to a terminal 14. As a result, the 2nd data signal is formed with the shorter pulse. The 2nd data signal is superimposed on a part of the synchronizing signal of the 1st data signal. As a result, the two signals are transmitted with the same carrier.
