255

256

Solution:

In the toggle mode, a JK flip-flop has

J = 0, K = 0

J = 1, K = 1

J = 0, K = 1

J = 1, K = 0

Solution:

The number of comparators required to build a 5-bit analog-to-digital converter is:

Solution:

The relationship between the output frequency and the sampling interval of a frequency counter is:

Directly proportional to the sampling interval

Inversely proportional to the sampling interval

More precise with a longer sampling interval

Less precise with a longer sampling interval

Solution:

Let (X₁, X₀) and (Y₁, Y₀) be unsigned 2-bit numbers. The function F = 1 if X > Y, and F = 0 otherwise. The minimized sum of expression for F is

Y₁.Y₀ + X₀.Y₀ + (X₁)'.(X₀)'.(Y₁)'

X₀.(Y₁)' + Y₁.(Y₀)' + X₁.(X₀)'

Y₁.(X₁)' + Y₀.(X₁)'.(X₀)' + Y₁.Y₀.(X₀)'

X₁.(Y₁)' + X₀.(Y₀)'.Y₁' + X₀.X₁.Y₀'

Solution:

Consider A and B as inputs and C as some carry or borrow to the combinational circuits, then A ⊕ B is the output to:-

Full - adder sum

Half-Adder sum

Full- Subtractor difference

All the above

Solution:

A 2:1 multiplexer (M1) has one of its inputs (I0) grounded and the other input (I1) connected to the NAND of two inputs A and B. The output of M1 is connected to the input I0 of another 2:1 multiplexer (M2). The input I1 of M2 is supplied with a high voltage. If the select lines of M1 and M2 are S1 and S2 respectively, and S1=1 and S2=0, what is the output of M2?

A' + B'

Solution:

With regard to a D latch ________

The Q output follows the D input when EN is LOW

The Q output is opposite the D input when EN is LOW

The Q output follows the D input when EN is HIGH

The Q output is HIGH regardless of EN’s input state
