What is the basic unit of digital electronics?

• bit

• kilobyte

• megabit

• byte

Explain the concept of logic gates in digital electronics.

• Logic gates are only applicable in analog circuits.

• Logic gates are physical barriers that prevent electricity from flowing through a circuit.

• Logic gates are used to control the temperature of electronic devices.

• Logic gates are fundamental building blocks of digital circuits that perform logical operations on one or more binary inputs and produce a single binary output.

What is the decimal equivalent of octal number 22.74?

• 19.9375

• 18.8375

• 18.945

• 18.9375

Discuss the importance of binary numbers in digital electronics.

• Binary numbers are crucial in digital electronics as they form the basis for representing data and performing logical operations efficiently.

• Binary numbers are not relevant in digital electronics.

• Binary numbers are not efficient for logical operations.

• Binary numbers are only used in analog electronics.

Octal equivalent of 247

• 376

• 367

• 377

• 387

Explain the working principle of an AND gate.

• The working principle of an AND gate is that it produces a high output (1) only when all of its inputs are high (1). If any of the inputs are low (0), the output will be low (0).

• An AND gate produces a low output when all inputs are high

• AND gate works by summing the inputs

• The output of an AND gate is always high regardless of inputs

What is the significance of truth tables in digital electronics?

• Truth tables are only relevant for analog electronics

• Truth tables are crucial in digital electronics for analyzing logic gates, circuits, and Boolean expressions.

• Truth tables help in debugging software programs

• Truth tables are used for designing physical circuits

Describe the process of binary addition in digital circuits.

• The process of binary addition in digital circuits involves adding two binary numbers bit by bit, handling carries appropriately.

• Binary addition involves multiplying the numbers instead of adding them.

• In binary addition, carries are ignored and not considered in the calculation.

• The process of binary addition in digital circuits is the same as decimal addition.

What are the different types of Bipolar logic families used in digital electronics?

• Saturated and Uni-polar and Bipolar

• Uni-polar and Bipolar

• Unipolar and Non-Saturated

• Saturated and Non-Saturated

What is Fastest logic circuit in digital systems.

• BCL

• ECL

• TTL

• CMOS
