Directions to Solve

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

Q1: HYPOCRITICAL

A Dependable

B Gentle

C Amiable

D Sincere

Q2: Which of the following statements are correct about the below program? 
#include<stdio.h>
int main()
{
    int n = 0, y = 1;
    y == 1 ? n=0 : n=1;
    if(n)
        printf('Yes\n');
    else
        printf('No\n');
    return 0;
}

A Error: Declaration terminated incorrectly

B None of above

C Error: Lvalue required

D Error: Syntax error

Q3: The main concern when using a pull-down resistor is:

A it will keep a floating terminal LOW

B it will cause false triggering

C the low power dissipation of the resistor

D the high power dissipation of the resistor

Q4: Look up the propagation delay from the clock to the output for the 7476. Are the HIGH-to-LOW and LOW-to-HIGH propagation delays the same?

A no, tPHL = 25 ns, tPLH = 40 ns

B no, tPLH = 25 ns, tPHL = 40 ns

C no, tPLH = 40 ns, tPHL = 25 ns

D yes

Q5: What would be the output voltage of a 7814 voltage regulator?

A +14 V dc

B –14 V dc

C –8 V dc

D +8 V dc

Q6: The purpose of a pull-up resistor is to keep a terminal at a ________ level when it would normally be at a ________ level.

A pulsed, float

B LOW, float

C clock, float

D HIGH, float

Q7: Setup time specifies:

A how long it takes the output to change states after the clock has transitioned

B the minimum time the control levels need to be maintained on the inputs prior to the triggering edge of the clock in order to be reliably clocked into the flip-flop

C how long the operator has to get the flip-flop running before the maximum power level is exceeded

D the maximum time interval required for the control levels to remain on the inputs before the triggered edge of the clock in order for the data to be reliably clocked out of the flip-flop

Q8: Can the automatic RC circuit be used to set a flip-flop rather than reset the flip-flop?

A yes

B no

Q9: A Schmitt trigger:

A has two trip points

A set

B toggle

C reset

D dual
