Solution:

The initial values in all the cells of an EPROM (Erasable Programmable Read-Only Memory) are

Both 0 and 1

Either 1 or 0

Solution:

Which type of memory can solely perform the following tasks on a computer?

Loading of applications

Browsing the internet

Editing a spreadsheet

HHD

EPROM

RAM

Solution:

Which of the following Boolean expressions best represents the consensus theorem?

AB + A'C + BC = AB + A'C

AB + A'B + AB' = A+B

AB + A'C + BC = AB + A'B

A +BC = (A + B)(A + C)

Solution:

What configuration feature of NOR and NAND gate-based latches causes them to remain in the latched condition?

Low input voltages

Synchronous operation

Gate impedance

Cross coupling

Solution:

Which of the following expressions represents the correct next state Qn+1 equation for a JK flip-flop given the present state Qn?

Qn+1 = J Qn' + K' Qn

Qn+1 = J Qn + K Qn

Qn+1 = J' Qn + K Qn

Qn+1 = J' Qn' +K Qn

Solution:

Two 4-bit sequences A(1101) and B(0010) are applied to a full adder. What are the values stored in the sum (S) and carry (C) outputs, assuming the carry-in (Cin) is 1?

C=0, S=0000

C=1, S=1111

C=1, S=0000

C=0, S=1111

Solution:

Based on how the data is received and transmitted in the registers, how many types of registers are there?

2

3

4

5

Solution:

A square wave of frequency 300 Hz is sent as an input to a positive edge-triggered MOD 3 counter. The output of the counter is sent to a negative edge-triggered D flip-flop. The final output is found when the output of the counter and the output of the D flip-flop are ORed. What is the frequency and duty cycle of the final output waveform?

150 Hz, 75%

100 Hz, 50%

100 Hz, 25%

150 Hz, 30%
