Circuit analysis is an important basis for solving circuit problems. As long as it is a circuit, as long as it is to solve the basic electrical quantity, it must be solved by the basic method of circuit analysis. So as long as your major is related to electricity, circuit analysis must be studied.

Digital electricity is actually a math course, which runs through a very simple math system: logical algebra. Only when the principle of gate circuit is discussed at the beginning will very simple circuit and semiconductor knowledge be used. After that, the sequential circuits of combinational circuits are all logical algebra problems. The so-called analysis and design are only logical operations, and the so-called circuit diagram is only a graphical expression of some operational symbols. Later, some transition process analysis is needed in waveform generation and shaping, but in the application stage, without basic circuit foundation and knowledge of transistor diode principle, you will encounter many "metaphysical" problems. In fact, you don't need a lot of circuit theory to cope with the electricity test.
