Assignment Help:

Distinguish between combinational logic circuits and sequential logic circuits.

Ans:

Combinational logic circuits:-

(i) Outputs only depend upon present state of the input.

(ii) No memory element present or no feedback connection.

Sequential logic circuit:-

(i) Output not only depends upon the recent state of the input but also depend upon the earlier state of the output.

(ii) Memory component is present or a feedback connection is there.
