08․ A D-flip-flop is said to be transparent when
the output is LOW
the output is HIGH
the output follows clock
the output follow input
When the clock is enabled (en=1) for a D-flip-flop, the input is appeared at the output. So the flip-flop is said to be transparent.
09․ Which of these sets of logic gates are designated as universal gates?
NOR, NAND.
XOR, NOR, NAND.
OR, NOT, AND.
NOR, NAND, XNOR.
NAND or NOR gate can design all other logic gates. So, they are designated as universal gates.
10․ Which one of the following is not a vectored interrupt?
TRAP.
RST 7.5.
RST 6.5.
INTR.
In 8085 microprocessor TRAP, RST 7.5, RST 6.5, RST 5.5 are vectored interrupt. But RST 3 and INTR is a non vectored interrupt.
