ABSTRACT:
Signal transmission method and apparatus is an input unit for inputting signals through operation of keys. Addresses of the operated keys are extracted through scanning and sent to a signal processing unit, while signals from the signal processing unit are subsequently received. For allowing the scanning to be performed even at the times of signal sending and reception, the scanning period is divided into a number of intervals equal to the numbers of bits which constitute the signal to be transmitted, wherein the sending and reception of the signal to be transmitted are performed in synchronism with the scanning intervals.
