2 Logic families of IC having dense packing density, simpler processing techniques and more economic operations are :
A TTL
B ECL
C CMOS
D None of the above

Answer: Option [C]

CMOS (Complementary Metal Oxide Semi-Conductor) uses PMOS and NMOS transistors which are connected in a complementary fashion in all circuits and provides high packing density with simpler precessing technique & more economic operation.

3 Using an additional NOT gate, a JK flip-flop can be converted into
A T flip-flop
B RS flip-flop
C Master Slave flip-flop
D D flip-flop

Answer: Option [C]

To construct master slave flip-flop additional NOT gates are added to the circuit.

4 Which of the following logic families is well suited for high speed operations ?
A TTL
B ECL
C MOS
D CMOS

Answer: Option [D]

CMOS is a logic family, provides minimum power dissipation and higher voltage swing.
