What is the maximal length of bit pattern associated with a LFSR with the same number of outputs as that of figure Q7? State the criteria which must hold for a LFSR to be of maximal length. Show, by using a characteristic polynomial or by any other means, that the pseudo-random sequence generated by this circuit is not of maximal length. Describe the operation and purpose of the logic gates labeled A and B in the operation of the circuit. cik 6-bit paraliel out chit neilleher

Latches and Flip Flop

Just like logic gates, the latches and flip-flops are the important elements of an electronic circuit. The logic gates form the important part of combinatorial circuits, while the latches and flip-flops form the essential part of a sequential circuit. Sequential circuits form the important concept of automata theory in electronics and electrical engineering, these circuits are a kind of logic circuit whose output depends on both present input and past inputs, that is, the input history.
