英语翻译The nature of electrical signals in electronic circuits

英语翻译The nature of electrical signals in electronic circuits readily enables the technology to be divided into classes.One of the classes is analog electronics; another is digital electronics.Both analog and digital electronics use similar electronic elements,but the manner of use is different,and the technologies appear to be quite distinct.For this reason we shall study them separately until we bring them together as they invariably unite in instrumentation and applications.
