In the following questions choose the word which is the exact OPPOSITE of the given words.

Q1: ADHERENT

A Enemy

B Alien

D Detractor

Q2: What will be the output of the program? 
#include<stdio.h>
int main()
{
    int a=0, b=1, c=3;
    *((a) ? &b : &a) = a ? b : c;
    printf('%d, %d, %d\n', a, b, c);
    return 0;
}

A 1, 2, 3

Q4: The quantization error in an analog-to-digital converter can be reduced by:

A decreasing the number of bits in the counter and increasing the number of bits in the DAC.

B decreasing the number of bits in the counter and DAC.

C increasing the number of bits in the counter and DAC.

D increasing the number of bits in the counter and decreasing the number of bits in the DAC.

Q5: One disadvantage of the tracking A/D converter is:

A that the binary output will oscillate between two binary states when the analog input is constant.

B the need for a latch and its associated control circuit.
