Top List of Digital Electronics Projects with Abstract for Engineering Students

Nowadays, most of the modern electronic devices such as computers, mobile phones work with digital electronics. Digital electronics projects use a digital signal instead of an analog signal for their operation. There are many benefits of using digital signals in place of analog signals, viz. speed of operation, data protection, reproducibility, etc. The best examples of digital electronic systems are mobile phones in which voice is converted into a series of electronic pulses as digital (or 0s and 1s) and then transmitted to the receiver end where these digital pulses get converted back into a voice. The logic gate is the common fundamental unit of digital electronics and basic gates include three types: AND, OR, and NOT. Two universal gates NAND and NOR gates are made of these three basic gates. These Digital logic circuits are integrated into a single IC to design several processors and controllers.

In this article, we are providing some digital electronics projects with abstracts for engineering students and for those who are interested to do projects on digital electronics. The following are some of the latest digital electronic projects with the abstract.
