When we talk about electronics, surely it will never be separated from the name electronic circuit. Because one of the outputs of learning electronics is being able to create and improve electronic circuits. Currently, we are familiar with various kinds of electronic circuits, ranging from simple to complex.

In every electronic device that we encounter everyday, there must be an electronic circuit inside. Call it television, radio, refrigerator, washing machine, and many other electronic devices that rely on electronic circuits as the brain or control. If you look at the definition, an electronic circuit is a set of electronic components that are assembled into a single unit so that they have a specific function.

Electronic circuits are electrical circuits or electrical circuits that use active electronic components such as transistors and integrated circuits (IC chips). Electronic circuits can be very complex, although they use the same basic principles as in ordinary electrical circuits. Electronic circuits are usually categorized into three parts: analog circuits, digital circuits, and combined circuits between them.

Analog electronic circuits are concerned with signals that change continuously (finely or gradually) according to the information they contain. Some electronic equipment such as amplifiers, tuners, radios, and televisions use analog signals mainly on the front and ends. The main components in analog electronic circuits are passive components (such as resistors, capacitors, inductors and transformers), and active components (such as transistors, diodes, FETs, CMOS, etc.).

In digital electronic circuits, the electric signal used changes discrete (high or low) according to the logical value (1 or 0) of the information to be processed. Electronic components that use digital signals include logic gates, digital clocks, calculators, PDAs (Personal Data Assistants or pocket computers), microprocessors, and computers.

Combined electronic circuits contain both analog and digital signals. Some examples of circuits that use these two types of signals are comparators, counters (timers), PLL, ADC (Analaog-to-Digital Converter), and DAC (Digital-to-Analog Converter). In the learning application of electronic circuits, there are several kinds of simple electronic circuit schemes that you can find out about, Hopefully this electronic circuit learning application can be helpful and useful for you, thank you.
