Logic Circuits Final Summative Test C

The 2421 code falls under which type of binary code?

• Sequential code

• Gray code

• Weighted code

• Non-weighted code

These are the storage elements used in clocked sequential circuits.

• Latches

• Clock pulses

• Flip-flops

• Binary codes

Which best describes the toggle latch?

• Its circuit output changes only at some discrete instants of time.

• Its circuit output can change at any time.

• It is an improvement of the gated SR latch because it prevents the problem when both inputs are logic 1.

• It is formed when the inputs of the JK latch are shorted.
