DATA COMMUNICATION METHOD, TRANSMITTER AND RECEIVER

摘要

PURPOSE: To attain accurate pulse width communication in the case of communication between different microcomputers by correcting pulse width of a transmission pulse signal to decode transmission data when a received pulse signal is a transmission pulse signal of a transmitter side. CONSTITUTION: A correction data generating means in a transmitter A outputs 1st and 2nd correction data sequentially discriminated from transmission data to a coding means prior to the transmission of a transmission pulse signal from a pulse signal transmission means and the coding means converts the both into 1st and 2nd correction pulse signals. Then a pulse signal transmission means sends the 1st and 2nd correction pulse signals sequentially. When a pulse signal discrimination means of a receiver B discriminates the pulse signal to be the transmission pulse signal, a transmission data correction means corrects the decoded transmission data based o a clock error and a delay error calculated by a clock error calculation means and a delay error calculation means.
