What is circuit in PCB design and what are the electronic routes?

In our life, we should all see the messy circuit lines. They look messy, but they still have a lot of knowledge. Today, I will introduce circuit design. Circuit design refers to the design of circuit systems that meet the requirements of use according to certain rules and using specific methods. Circuit board design is also called electronic circuit design. Next, let me introduce to you what is circuit and what are the electronic routes?



1、 What is a circuit

Circuit (electronic circuit) is a general system that is connected by electrical equipment and components in a certain way to provide a path for current flow, also known as electronic network. The size of the circuit can vary greatly, from the integrated circuit on the silicon chip to the power transmission network. Circuit (English: Electrical circuit) or electronic circuit is a general system that is connected by electrical equipment and components in a certain way to provide a path for charge flow. It is also called electronic circuit or electrical circuit, or network or circuit for short. Such as resistance, capacitance, inductance, diode, triode and switch, etc.

2、 What are the electronic routes?

According to the different signals processed, electronic circuits can be divided into analog circuits and digital circuits.

(1) Analog circuit

Analog circuit is a continuous physical natural variable that produces periodic changes from nature. The circuit that converts continuous physical natural variables into continuous electrical signals and calculates continuous electrical signals is called analog circuit. The analog circuit processes the continuous voltage and current of the electrical signal. The most typical analog circuit applications include: amplification circuit, oscillation circuit, linear operation circuit (addition, subtraction, multiplication, division, differential and integral circuit). Calculate continuous electrical signals. Circuit board design and circuit board processing manufacturers explain what circuits are, and what are the electronic routes?

(2) Digital circuit

Digital circuits are also called logic circuits

A circuit that converts continuous electrical signals into discontinuous quantitative electrical signals and calculates discontinuous quantitative electrical signals is called a digital circuit. In digital circuits, the signal size is discontinuous and quantized. Most of them use Boolean algebra logic circuit to process the quantitative post signal. Typical digital circuits include oscillator, register, adder, subtracter, etc. Quantitative electrical signal of operational discontinuity.

(3) Integrated circuit

Integrated circuit is an integrated and miniaturized circuit, also known as integrated circuit, IC (English: Integrated Circuit)

·A semiconductor circuit (generally called a silicon chip) that uses an integrated circuit design program (IC design) to design general circuits into semiconductor materials is called an integrated circuit.

·Integrated circuits (ICs) are manufactured using semiconductor technology.

RF circuit

·It refers to the circuit used for high-frequency and ultra-high frequency electromagnetic wave with space long-distance transmission characteristics

·Radio frequency (RF for short) refers to radio frequency current, which is the abbreviation of high-frequency alternating electromagnetic wave. Alternating current with a change of less than 1000 times per second is called low-frequency current, while that with a change of more than 1000 times is called high-frequency current, and radio frequency is such a high-frequency current. The cable TV system adopts the radio frequency transmission mode.

In the theory of electronics, when current flows through a conductor, a magnetic field will form around the conductor; When the alternating current passes through the conductor, the alternating electromagnetic field will be formed around the conductor, which is called electromagnetic wave.

When the electromagnetic wave frequency is lower than 100kHz, the electromagnetic wave will be absorbed by the surface and cannot form an effective transmission. However, when the electromagnetic wave frequency is higher than 100kHz, the electromagnetic wave can spread in the air and be reflected by the ionosphere at the outer edge of the atmosphere to form a long-distance transmission capability. We call high-frequency electromagnetic wave with long-distance transmission capability radio frequency, abbreviated as RF.

The above is my answer to "What are circuits and what are the electronic routes?" The introduction of, provide you with reference, wish you a happy life! Circuit board design and circuit board processing manufacturers explain what circuits are, and what are the electronic routes?
