1 *Sequential logic circuit:. It is consist of logic getes and storge element (memory element )the o\p depend of i\p and the past i\p the flip flop circuit sitis the basic desigen of it. The system whose behavior can be defined form the know lodge of its signal at descrete of time.. The system whose behavior can be defined form the know lodge of its signal at descrete of time..

2 The storge element(memory)use in clocked sequential cct are called llip flop… Is binary storge device capuble of storge one bit of information. Asequential cct my use many flip flops to store as many bits as no necessary,,
