BCA Semester 1 – Digital Logic – Unit 4: Counters & Registers

What are the drawbacks of clocked RS Flip Flop? Explain the operation of JK Flipflop along with its circuit diagram and characteristic table.

What is T-Flip Flop? Explain clocked JK Flip-Flop with its logic diagram and truth table.

Explain JK and T Flip Flop with their Logic and Diagram, graphical symbol, characteristic table, characteristic equation and excitation table.

Explain clocked JK flip flop with logic diagram, truth table, characteristic table and excitation table.

What is race around condition? Explain how JK master flip flop is used to eliminate race around condition.

What is register? Explain types of registers depending on input output with its block diagram & logic diagram.

What is a synchronous sequential circuit? Explain RS NAND latch with block diagram, logic diagram, truth table, and timing diagram.

Define register. Explain serial-in serial-out register with working mechanism for data input 11010

How does a flip-flop differ from a latch? Explain clocked SR flip-flop with logic diagram, truth table, characteristic table, and excitation table.

Explain how race condition in JK flip-flop can be resolved. A sequential circuit with two D Flip-Flops (A, B), inputs x,y, and output z is defined by:

$A(t+1)=xy′+xB$

$B(t+1)=x′B+xA$

$z=A$
