Solution:

In the toggle mode, a JK flip-flop has

J = 0, K = 1

J = 1, K = 1

J = 0, K = 0

J = 1, K = 0

Solution:

Arrange the following in descending order of 'speed of conversion'-
A. Parallel Comparative ADC
B. Dual Slope ADC
C. Successive Approximation ADC
D. Counter Type ADC

C,A,B,D

B,D,C,A

A,C,D,B

D,B,A,C

Solution:

Consider a sequential circuit with three inputs, A, B, and C, and two outputs, X and Y. The truth table for this circuit is given below:
What is the logic expression for the output Y in terms of the inputs A, B, and C?

Y = (A ⊕ B) ⊕ C

Y = (A ⊕ B) ∧ C

Y = A ⊕ (B ∧ C)

Y = A ⊕ (B ⊕ C)

Solution:

Without adding any additional circuitry, an 8:1 MUX can be used to get:

all boolean functions of 3 variables but none of 4 variables

all boolean functions of 3 variables and only some of 4 variables

all boolean functions of 4 variables and only some of 4 variables

only some boolean functions of 3 variables

Solution:

What is the characteristic of a Master-slave flip flop?

Any change in the input gets immediately reflected in the output

Change in output only when the state of master is subject to change

Change in output only when the state of slave is subject to change

Change in output only when both master and slave are subject to change at the same time

Solution:

What are the primary functions of an Analog-to-Digital Converter (ADC) and a Digital-to-Analog Converter (DAC) in digital electronics?

Both ADC and DAC convert digital signals to analog signals.

ADC converts analog signals to digital signals, while DAC converts digital signals to analog signals.

ADC converts digital signals to analog signals, while DAC converts analog signals to digital signals.

Both ADC and DAC convert analog signals to digital signals.
