These circuits operate on continuous valued signals commonly referred to as analog signals. These circuits operate on signals that exist only at two levels i. Analog circuits are difficult to design since each component has to be placed by hand as automation techniques for designing these circuits fail to do the job efficiently.
On the other hand digital circuits are easy to design since automation technique can be applied at various levels of circuit design. No conversion of input signals are required before processing i. In digital circuits, the input signals are converted from analog to digital form before it is processed, i. In analog circuits, since there are no conversions involved at the input or at the output side there is no loss of information that is available for processing.
Due to the conversion process at the input side analog to digital and at the output side, some amount of information is lost during the conversion process. The man power available to design analog circuits is very low, this results in long time to market the finished products.

Share on Facebook. Follow us. The downside of an analog circuit is that their signal may get distorted and causes to lose the information. Therefore, the accuracy or precision of such circuits deteriorates. Also, they are difficult to design since the components are placed manually.
The type of electronic circuit that processes data or signal that has discrete amplitude also known as the digital signal is called a digital circuit. They are made from digital logic gates which is the basic building block of any digital circuit. Since the digital circuit only operates on digital signal, therefore the real-world analog signal much be changed into a digital signal using ADC Analog to Digital Converter which can cause loss of information due to sampling.
The output digital signal must be converted back into an analog signal using DAC Digital to Analog Converter if they are supposed to interact with the real-world components. The digital circuits can be only Active circuit i. Because the digital circuits are made from transistors, it is impossible to make a passive digital circuit.
However, most of the digital circuits need a clock signal a signal oscillating between high and low state to synchronize the operation of the circuit.
It tells the circuit when and how to operate the next command. The following comparison table shows the main difference between digital and analog circuits. It is the same question like which number is better, 0, 1 or 39?.
To the question, it depends on the applications based on multiple factors. Both digital and analog have advantages and disadvantages. Related Posts:. Your email address will not be published.
