Analog and Digital- the basics of the circuits in Electronics


Electronics branches out with several of its sub-genres such as digital electronics, analog electronics, consumer electronics, and power electronics amongst others. The electronic tutorials on analog and digital circuits are a great help when one is trying to grasp the concepts for practical use.

Taking a look at the basic sub fields of electronics, the analog and the digital, what are the basic components that divide the two? Apart from the basic difference of digital circuits being more flexible than analog ones which are custom made, there is a wide difference between both the forms of circuit. The fundamental components of electronics such as inductors, resistors, diodes, and capacitors inherently function based on the principles of analog electronics. The circuits that work with these electronic parts are mostly analog. If one refers to any analog electronic tutorial, it is evident that these circuits function with the help of continuing signals of value which are termed as analog signals. Analog circuits are either intricately designed or simplistic in nature. Although designing an analog circuit is tougher than a circuit that is digitally designed, many digital components are utilised to ease out the process of designing several analog circuits. But unlike digital signals, an analog circuit does not require signal conversions and an input signal which is analog in nature will automatically produce an analog output. And one advantage this direct input and output procedure provides is that there is no loss of information during the process, unlike the digital circuits. Though an important and a really basic subject form of electronics, analog circuits are more prone to being affected by voltage variations and other sound disturbances.


Digital circuits however, are a comparatively newer subfield and work using more developed and discrete signals. A combined system of transistors and logic gates and for higher levels of circuits, microcontrollers are used. The most common example of digital circuit functioning is the microprocessor. Tutorials on digital electronics are a better way of studying the subject as they help in understanding the ways in which a digital circuit uses binary signals to process its instructions.

Analog and Digital circuit systems can be combined to facilitate conversions of signals in a better way as in the case of some microcontrollers, who have a digital system in working but have internal circuits that work well with analog signals for conversions from one to the another. One can learn more from the videos on electronic tutorials about the co functioning of analog and digital circuits.
