Integrated,digital and advanced electronics

What is the output waveform?

• sine wave

• square wave

• sawtooth wave

• triangle wave

The open-loop voltage gain (A_ol) of an op-amp is the

• external voltage gain the device is capable of

• internal voltage gain the device is capable of

• most controlled parameter

• same as A_cl

the circuit is a

• a low-pass filter

• a high-pass filter

• a bandpass filterr

• a band-stop filter

The op amp configuration employed in the construction of a low pass filter is

• noninverting

• inverting

• comparator

• open-loop

how can we decrease the gain

• reducing the amplitude of the input voltage

• increasing the value of the feedback resistor

• increasing the value of the input resistor

• removing the feedback resistor

The output of the circuit will be:

• A . B

• (A+B)'

• A'. B'

• (A.B)'

The number of inputs for a OR gate is 6. The number of input words in its truth table is:

• 6

• 32

• 64

• 128

NAND gate is called a universal gate, since

• It is used by everybody

• Any logic function can be realized by NAND gates alone

• All the minization techniques are applicable for optimum NAND gate realization

• Many digital computers use NAND gates.

In the toggle mode a JK flip-flop has

• J = 1, K = 1

• J = 0, K = 0

• J = 1, K = 0

• J = 0, K = 1

In an SR latch built from NOR gates, which condition is not allowed

• S=1, R=1

• S=0, R=1

• S=1, R=0

• S=0, R=0
