Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. … Digital electronic circuits are usually made from large assemblies of logic gates, often packaged in integrated circuits.
What is the use of digital electronics?
Many of our household items make use of digital electronics. This could include laptops, televisions, remote controls and other entertainment systems, to kitchen appliances like dishwashers and washing machines. Computers are one of the most complex examples and will make use of numerous, complex circuits.

…
- Flip-Flops and Sequential Circuits.
- Register and Counters.
- Memory and Programmable Logic.
- Data Communication.
- Quick Links.
How does digital electronics work?
Digital electronics are electric circuits that work on only two fixed values: “1” and “0”. They use a series of 1’s and 0’s to store and communicate information. They can also perform math using just 1’s and 0’s. This is called Boolean math or Boolean logic.
Difference Between Analog And Digital Signal
Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals that have continuous electrical signals, while digital signals have non-continuous electrical signals. The difference between analog and digital signal can be observed with the various examples of different types of waves.
Analog Signals
The analog signals were used in many systems to produce signals to carry information. These signals are continuous in both values and time. The use of analog signals has been declined with the arrival of digital signals. In short, to understand the analog signals – all signals that are natural or come naturally are analog signals.
Digital Signals
Unlike analog signals, digital signals are not continuous, but signals are discrete in value and time. These signals are represented by binary numbers and consist of different voltage values.
Difference Between Analog and Digital Signal
We know that the major difference between analog and a digital signal is that analog signals are continuous signals, while digital signals are discrete signals. In the video below we have discussed more differences between them.
32,455
Summarising, we have given the various differences between analog and digital signal in a tabular form below.
Both these signals are used in electronics communications systems to transfer information from one place to another.To learn more differences or other related topics, download BYJU’S – The Learning App.

THEN WHAT IS BCD CODE IN DIGITAL ELECTRONICS?
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow)
What is BCD code example?
Examples. The BCD or binary-coded decimal of the number 15 is 00010101. The 0001 is the binary code of 1 and 0101 is the binary code of 5. Any single decimal numeral [0-9] can be represented by a four bit pattern.
What is the use of BCD code?
Binary-coded Decimal or BCD is a way of representing a decimal number as a string of bits suitable for use in electronic systems. Rather than converting the whole number into binary, BCD splits the number up into its digits and converts each digit to 4-bit binary.
How do I find my BCD code?
In BCD code, each digit of the decimal number is represented as its equivalent binary number.
…
Example 1: (11110) 2.
| Binary Code | Decimal Number | BCD Code |
|---|---|---|
| 0 1 1 1 | 7 | 0 : 0 1 1 1 |
| 1 0 0 0 | 8 | 0 : 1 0 0 0 |
| 1 0 0 1 | 9 | 0 : 1 0 0 1 |
| 1 0 1 0 | 10 | 1 : 0 0 0 0 |
How many bits is a BCD code?
four bitsBCD encodes each decimal digit with its binary equivalent using four bits. So decimal digits are simply represented in four bits by their direct binary values. A disadvantage of this is that only 10 of the possible 16 (24) codes that four bits can produce are used.
