Draw the gate level circuit schematic of a D flip-flop and a T flip-flop based on the cross-coupled NAND latch. Briefly discuss the timing behavior of a D flip-flop, a T flip-flop and a latch. (a) (8 Marks) circuit has three inputs, S, C and C2. S is the control input. When S-O, the circuit behaves like a D flip-flop, and when S-1, the circuit behaves like a T flip-flop. The input characteristics of the circuit are tabulated in Table...

23. A J-K flip-flop has a l on the J input and a 0 on the K input. What state is the flip-flop in? (a) Q=1,0-0 (b) Q-1, Q-1 (c) Q-0,Q 1 (d) Q-0,Q-0 -24. On a positive edge-triggered S-R flip-flop, the outputs reflect the input condition when (a) the clock pulse is LOW (b) the clock pulse is HIGH (c) the clock pulse transitions from LOW to HIGH (d) the clock pulse transitions from HIGH to LOW 25. The...

Your reset may be synchronous or asynchronous. Assume any input, output, or signal variables that you require have already been declared in VHDL (you do not have to write the declarations for these) b) [I pal ls your reset syachronous or asynchronous for the D-Flip Flop...
