Let L = (0+1)*1(0+1)^(n−1) and following statements regrading language L: The language L can be recognised by a non-deterministic automaton with (n+1) states. Deterministic automaton recognises this language must have at least 2^n states. (Assume n≥1). Which of the ... ---------- According to me, L can be written as (0+1)*1(0+1)* which makes option D most suitable.

Testbook Test Series: Digital Logic - Digital Counter
A ripple counter with J-K flip-flop can be made to count down rather than up by i. Connecting the Q dash output to the input of the next stage, rather than the Q output ii. Making the output transition to occur at the rising edge rather ... output will be 0,1,2,3.... and if we invert the binary output of each gate then the count is reversed.
