DTMF is a reliable and mature technology. Because it can provide the higher dialing speed, it has rapidly replaced the dial pulsing signal which the traditional dial telephone used.
Based on much literature, the principle of the DIAL system in detecting chemicals and the various factors that influence the laser signal intensity are investigated in detail in this paper.
