In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data is stored in memory devices called flip-flops or latches. The output of a flip-flop is constant until a pulse is applied to its "clock" input ...
Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs include important analog design considerations.

Top students are invited to participate in the contest. Students in the Junior, Intermediate, and Senior divisions start in the morning with a 3-hour block in which to solve 2 programming problems. All divisions have a one-hour quiz (20 multiple choice questions) on topics that are covered in the written questions in the Regular Season rounds.
Mixed-signal ICs process both analog and digital signals together. For example, an analog-to-digital converter (ADC) is a typical mixed-signal circuit. Mixed-signal ICs are often used to convert analog signals to digital signals so that digital devices can process them.
In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without interference from the ...
The examination for all the papers is carried out in an online Computer Based Test (CBT) mode where the candidates are shown the questions in a random sequence on a computer screen. The questions consist of some Multiple Choice Questions or MCQs (four answer options out of which only ONE is correct, which has to be chosen).
This device was the first of its kind to combine circuit-board electronics with the ability to provide students with immediate positive feedback in monitoring answers to multiple choice questions. Subsequently, the electronic corrector was developed alongside a series of language courses which sold millions of copies worldwide throughout the ...
