Directions to Solve

Each sentences below consist of a word or a phrase which is bold. It is followed by four words or phrases. Select the word or pharse which is closes to the OPPOSITE in meaning of the bold word or phrase.

Q1: Mala was often teased as corpulent by her friends.

A fat

B gaunt

C garrulous

D belligerent

Q2: What will be the output of the program? 
#include<stdio.h>
#define PRINT(i) printf('%d,',i)

int main()
{
    int x=2, y=3, z=4;
    PRINT(x);
    PRINT(y);
    PRINT(z);
    return 0;
}

A 2, 2, 2,

B 4, 4, 4,

C 3, 3, 3,

D 2, 3, 4,

Q3:
The device shown here is most likely a ________.

A demultiplexer

B parity generator

C multiplexer

D comparator

Q4: In VHDL, macrofunctions is/are:

A digital circuits.

B preprogrammed TTL devices.

C a set of bit vectors.

D analog circuits.

Q5: Which of the following expressions is in the product-of-sums form?

A AB + CD

B (A + B)(C + D)

C AB(CD)

D (AB)(CD)

Q6: Which of the following is an important feature of the sum-of-products form of expressions?

A The delay times are greatly reduced over other forms.

B The maximum number of gates that any signal must pass through is reduced by a factor of two.

C No signal must pass through more than two gates, not including inverters.

D All logic circuits are reduced to nothing more than simple AND and OR operations.

Q7:
For the device shown here, assume the D input is LOW, both S inputs are LOW, and the input is LOW. What is the status of the outputs?

A All but  are HIGH.

B All but  are LOW.

C All are LOW.

D All are HIGH.

Q8: An output gate is connected to four input gates; the circuit does not function. Preliminary tests with the DMM indicate that the power is applied; scope tests show that the primary input gate has a pulsing signal, while the interconnecting node has no signal. The four load gates are all on different ICs. Which instrument will best help isolate the problem?

A Oscilloscope

B Logic probe

C Logic analyzer

D Current tracer

Q9: The binary numbers A = 1100 and B = 1001 are applied to the inputs of a comparator. What are the output levels?

A A > B = 0, A < B = 1, A = B = 1

B A > B = 1, A < B = 0, A < B = 1

C A > B = 1, A < B = 0, A = B = 0

D A > B = 0, A < B = 1, A = B = 0

Q10: A logic probe is placed on the output of a gate and the display indicator is dim. A pulser is used on each of the input terminals, but the output indication does not change. What is wrong?

A The dim indication is a result of a bad ground connection on the logic probe.

B The output of the gate appears to be open.

C The gate may be a tristate device.

D The dim indication on the logic probe indicates that the supply voltage is probably low.
