10 Questions
What is the main difference between combinational and sequential circuits?
Combinational circuits have outputs that depend only on the present inputs, whereas sequential circuits have outputs that depend on both current and previous values of the input signals.
What is the function of the memory module in a sequential circuit?
The memory module holds the state of the circuit.
What is the characteristic of combinational circuits in terms of their output?
The output of a combinational circuit depends only on the present inputs.
What is an example of a sequential circuit?
Registers, counters, and memory are examples of sequential circuits.
What is the primary distinction between digital logics?
Digital logics are divided into combinational and sequential circuits.
What is the role of the combinational logic portion in a sequential circuit?
The combinational logic portion determines the output based on the current input values.
What is the purpose of Elmore's constant in combinational logic design?
Elmore's constant is used to calculate the delay in a combinational circuit.
What is the advantage of pass transistor logic in combinational circuit design?
Pass transistor logic reduces the transistor count and increases the speed of the circuit.
What is the primary goal of low power design principles in combinational logic circuits?
The primary goal is to minimize power dissipation.
What is the significance of transmission gates in combinational circuit design?
Transmission gates are used to implement logic functions with reduced transistor count and increased speed.
