Introduction: The term “integrated circuit†sounds very professional, and it makes our laymen puzzled. What exactly is an integrated circuit and where can it be used? Today, we will simply introduce to you the functions of integrated circuits. .
First, the definition of an integrated circuit is such that it is a miniature electronic device or component. A certain process is used to interconnect the transistors, resistors, capacitors, inductors and other components needed in a circuit to form a small or a few small pieces of semiconductor wafers or dielectric substrates and package them in a single package. It becomes a miniature structure with the required circuit functions; in simple terms, it can be understood as a collection of miniature electronic components.
Integrated circuit is a new type of semiconductor device developed in the late 1950s and the 1960s. It is through the oxidation, photolithography, diffusion, epitaxy, aluminum and other semiconductor manufacturing process, the semiconductor, resistors, capacitors and other components required to constitute a certain function of the circuit and the connection wires between them are all integrated in a small piece of silicon. On the chip, then solder the electronics packaged in a package.
At present, it is mainly used in all aspects of the computer field, including information appliances such as smart appliances can not be separated from its participation. Most of the chips in the computer are made up of it. Many smart appliances nowadays can only become "smart" because they have integrated ICs. This small IC contains thousands or even hundreds of millions of codes. The program is precisely because of these programs our lives can become more and more intelligent.
Alarm release mainly uses standard equipment such as audio alarms. During wartime, communication, broadcasting, and television systems must prioritize the transmission and issuance of air defense alarm signals, and auxiliary means such as sirens, horns, and gongs can also be used. The sound alarm must be set at the designated location, and the alarm facilities must be maintained in good working condition. The release and transmission of alarms should be fast and accurate, and multiple means should be used simultaneously; Strengthen communication and liaison with superiors, subordinates, and neighbors, receive air raid intelligence information at any time, strengthen observation of air targets, and promptly report air raid intelligence; According to the situation and duration of the air raid, timely release the warning signal. With the sudden increase of air raids, the increase of attack methods, and the expansion of destruction, the importance of air defense alerts is increasingly being valued. The accuracy, timeliness, and continuous issuance ability of air defense alerts are required to be higher. The issuance methods of air defense alerts will also become more flexible and diverse with the construction and improvement of communication and network.
