It may surprise you to learn that a technology that has been around for nearly two decades has paved the way for connected cars. ECall is old fashioned by high-tech standards, but it is now mandatory
This paper introduces a method of using a single chip microcomputer to identify telephone signal tones, which is low in cost, high in reliability and strong in adaptability. When the signal tone frequ
In a switching power supply, the excitation circuit is very important, especially when MOSFET is used as the main switch tube. The excitation circuit sometimes uses a single-ended forward circuit to e
