Electronic circuits can be defined as a combination of 2 or more electronics components either passive or active composite forming a system or function of simple signal processing and complex. Electronic circuits can be built with or without tension sources or current sources for operation. Visit China PCB for more information about electronic news.
To make a series of electronics required some parts as follows:
- Schematic of Electronics Circuit
An electronic circuit scheme is required as a guide in the manufacture of electronic circuits. The electronic circuit scheme should be designed or first designed before making the process of electronics. The process of making electronic circuit schemes can be done manually and with computer applications.
- PCB Assembly
PCB Assembly is a part that serves to assemble electronics components into electronic circuits. PCB Assembly is the result of the application of electronics circuit scheme that has been adapted to the physical form of components and layout of electronic components to create a signal processing system or function.

- Electronic Components
Electronic components are one of the main ingredients in making electronics circuits. The electronic components used to construct an electronic circuit are determined in accordance with the scheme of electronics made.
- Electronics Equipment
Equipment for making a series of electronics, in general, are solder, tang cut, taper pliers, screwdrivers and tin solder. The use of electronic equipment is tailored to the needs in the assembly of electronics.
Basically, every circuit of electronics is built with the aim to perform signal processing, be it analog signals or digital signals. Based on signal processing conducted by the series of electronics, the electronic circuit can be divided into several categories as follows.
- Analogue Electronics Circuits
The analog electronics circuit is a series of electronics constructed for the purpose of processing analog signals, these analog circuits can be constructed with 2 or more passive components as well as active components. In analog circuitry the signal given as a circuit input is a continuous signal (analog) which is generally a DC signal or a sinusoidal AC and an analogue electronics circuit will provide a continuous signal output (analog) both DC and a sinusoidal AC which has processed the signal in the form of voltage level, current or frequency.
- Digital Circuits
Digital electronics is a series of electronics built for the purpose of performing discrete (digital) signal processing. In the digital electronic circuit, the processed signal is always in 2 basic logic High (1) and Low (0). To make digital circuits always a voltage source from outside is required to supply digital circuits in order to operate. In the digital circuit, the given signal or an input is a digital signal and the circuit will give the output a digital signal as well.
- Combination Electronics Circuits
The combination of electronics is a series of electronics built for the purpose of processing analog and digital signals both simultaneously and gradually. Combined electronic circuits can perform continuous signal processing (analog) and produce discrete (digital) signals or vice versa. Examples of combinations of electronics that can process analog signals into digital signals are ADC (Analog to Digital Converter) circuits and electronic circuits that can process digital signals into analog signals are DAC (Digital to Analog Converter) circuits. The application of a combination of electronic circuits can be encountered in a series of interfaces between digital circuits or computers to analog circuits and vice versa.
Then based on the principle of work, the series of electronics can be divided into several categories as follows.
- Basic Electronics Circuit
The basic electronics circuit is a combination of two or more passive electronic components that have formed a signal processing system. For example, the simplest basic electronics circuits are voltage dividers, current dividers, RC filters, LC filters and RLC filters. Examples of such basic electronics can be said to be simple electronic circuits because they are built only by 2 or 3 passive electronic components that are assembled either in series or in parallel.
- Multilevel Circuits
The multilevel series of electronics is the development of basic electronics circuits in order to provide better performance than basic electronics. In multilevel electronics, circuits are generally constructed from basic electronics circuits plus a simple amplifier circuit composed of 1 level or several levels.
- Complex Electronics Circuit
A complex electronic circuit is a series of electronics formed from several basic and multilevel electronic circuits with several different signal processing functions arranged to form an integrated signal processing system. For example, complex electronics circuit is a power supply with current and voltage regulator, an audio mixer circuit, transmitter circuit or radio transmitter, an amplifier circuit and another electronic circuit.
The electronics circuits that have formed a signal processing system traded in electronics stores are often referred to as electronic kits. This is because the electronic product is or form a part of the electronic circuit which, when combined will form a complete system or electronic device. For example, to make a complete amplifier then we can buy Power Amplifier kit, Kit Tone Control, Power Supply Kit, Transformer, And Box Amplifier then we raft some kits and components so as to form a complete Power Amplifier of some series of electronics.
