Title:
DATA TRANSMISSION/RECEPTION SYSTEM
Document Type and Number:
Japanese Patent JP3222623
Kind Code:
B2
Abstract:

PURPOSE: To provide a data transmission/reception system where the number of both rise/fall edges and pulses is reduced to minimize the occurrent of noise.
CONSTITUTION: A duty generating means 3 which generates the duty of a corresponding transmission signal from m-bit data to be transmitted in one cycle, period generating means 7, 8, and 9 which generate the period of the transmission signal based on a communication rate, pulse duty generating means 4 and 5 which generate a pulse duty corresponding to the duty of the transmission signal generated by the duty generating means 3, and a pulse width modulation signal generating means 6 which generates a pulse width modulation signal based on the period of the transmission signal generated by period generating means 7, 8, and 9 and the pulse duty of the transmission signal generated by pulse duty generating means 4 and 5 are provided.
