Question

What is sequential circuits?

Answer 1

Sequential circuits are the basic electronic logic circuits build of basic logic gates. They do not have a memory element. so their present state depends on the present inputs only.

example  Multiplexers, decoders

Answer 2

Sequential logic circuits DO depend on the previous state:
