WIRELESS ELECTROMAGNETIC TRANSMISSION METHOD FOR DATA

摘要

PROBLEM TO BE SOLVED: To provide a method that attains transmission of data at a high transmission rate independently of the electric field strength of the signal data to be transmitted and that is available for signal data including a DC voltage component depending on contents of the signal data. SOLUTION: This method is a method that electromagnetically transmits data wirelessly. The data are binary signals transmitted from a transmitter as amplitude-modulated signals. A receiver receives the signals and converts the signals into rectangular signals 43 by means of an adjustable comparator threshold value 42 in this wireless electromagnetic transmission method. This method holds the width (b) of the demodulated pulse signals to be a prescribed target value at least partially by varying the comparator threshold value 42 to trace the pulse width (b).
