Introducing AC (Alternating Current) and DC (Direct Current) in Electronics

By | October 16, 2021

Introducing AC (Alternating Current) AC current is an electric current and voltage whose magnitude changes with time and flows in both directions. The direction of AC electric current does not move from the positive to the negative pole, but the current is alternating. An alternating current source works on the principle that the coil rotates… Read More »

In addition, DACs are a link between digital circuits and analog circuits. Digital… Read More »

Introduction to Analog to Digital Converters (ADCs) and How ADCs Works

By | August 12, 2021

Introduction to Analog to Digital Converters (ADCs) Analog to Digital Converters (ADCs) are circuits that convert continuous (analog) voltage values ​​into binary (digital) values ​​that can be processed by digital devices so that they can function as digital computing. With another definition, that this Analog to Digital Converter allows Digital circuits to interact with the… Read More »

FLIP-FLOP In Digital Systems

Flip-flops are asynchronous bistable components. The term asynchronous means that the output will change state only if there is a trigger on the clock input. The internal circuit of a flip-flop consists of several logic gates, while the logic gate consists of basic components such as transistors, resistors and diodes. In a computer system, the… Read More »
