PDF	Asynchronous Sequential Circuits -The design of these circuits is more difficult than the design of synchronous circuits due to the timing problem Page 4 Why Asynchronous Circuits?

Analysis and Design of Sequential circuits:

Derive the output function and the Flip-Flop input functions.

What is the analysis and design procedure of asynchronous sequential circuits?

The general steps to be followed for design of asynchronous sequential circuits are as follows :

1Create a state table or state diagram from the given problem statement.
2) Create a new reduced state table by removing all the redundant states.
3) Create the transition table.

What is the design approach to asynchronous circuits?

Asynchronous circuit design is characterized by the use of function blocks, asynchronous registers, and the absence of clock signals.
This means that the counters in asynchronous circuits do not receive inputs simultaneously, nor do they give outputs simultaneously.

How does an asynchronous sequential circuit work?

Asynchronous circuit (clockless or self-timed circuit) is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components.
Instead, the components are driven by a handshaking circuit which indicates a completion of a set of instructions.
