Digital Electronics Prototype PCB Assembly

      A digital circuit or digital integrated circuit is a complex circuit composed of many logic gates. Compared with analog circuits, it mainly processes digital signals (that is, signals are expressed in two states of 0 and 1), so it has a stronger anti-interference ability. Digital integrated circuits have various gate circuits, flip-flops, and various combinational logic circuits and sequential logic circuits composed of them. A digital system generally consists of a control unit and an operation unit. Driven by the clock, the control unit controls the operation unit to complete the actions to be performed. Through analog-to-digital converters and digital-to-analog converters, digital circuits can be connected to analog circuits.

Circuit research

     The main problem studied in digital circuits is the logical relationship between the state of the output signal ("0" or "1") and the input signal ("0" or "1"), that is, the logical function of the circuit.

The research methods of digital circuits are logic analysis and logic design, and the tools needed are logic algebra. (In positive logic, "0" is low level, "1" is high level, and there is no clear boundary between high and low levels)

Advantage

     The reasons why electronic devices process information from analog to digital processing are mainly in the following aspects:

• Good stability. Digital circuits are not as susceptible to noise as analog circuits.

• High reliability. In the digital circuit, it is only necessary to distinguish whether the signal is present or not, so the component parameters of the circuit can allow a large range of variation (drift).

• Can be stored for a long time. Digital information can be stored for a long time using certain media, such as tapes, magnetic disks, and optical disks.

• Easy for computer processing. In addition to the intuitive and accurate advantages of digital signal output, the most important thing is that it is convenient to use electronic computers to process information.

• Easy for high integration. Since the structure of the basic unit circuit in the digital circuit is relatively simple, and the components are allowed to have greater dispersion, this allows us not only to make many basic units on the same silicon chip, but also to achieve mass production. required yield.
