Σ m(1, 4, 5, 6, 7)

Σ m(2, 4, 5, 6, 7)

Π m(2, 4, 5, 6, 7)

Π m(2, 4, 5, 7)

Solution:

What is the minimum configuration of a decoder required to implement the given boolean functions: f1 = ∑m(2,3,11), f2 = ∑m(5,7,12), and f3 = ∑m(9,14)?

2:4 decoders

3:8 decoders

4:16 decoders

5:32 decoders

Solution:

Why is a demultiplexer called a data distributor?

The input will be distributed to one of the outputs

One of the inputs will be selected for the output

The output will be distributed to one of the inputs

Single input to Single Output

Solution:

Implement the given function f(a,b,c) = ∑ (0,1,2,7) using a 4:1 MUX having a and b as select lines and d₀d₁d₂d₃ as the data lines. Select the correct data line values from the given options.

(Assume that the MUX is enabled and when a = 0 and b=0, d₀ is selected.)

d₀ = c̅, d₁ = 1, d₂ = 0, d₃ = c

d₀ = 1, d₁ = c̅, d₂ = 0, d₃ = c

d₀ = 0, d₁ = 1, d₂ = c, d₃ = c̅

d₀ = c̅, d₁ = 0, d₂ = c, d₃ = 1

Solution:

An 8-bit serial in/serial out shift register is used with a clock frequency of 150 kHz. What is the time delay between the serial input and the Q3 output?

1.67 s

26.67 s

26.7 ms

267 ms

Solution:

Reset inputs are used in IC 7490, why?

For increment of bit by 1

For decrement of bit by 1

For reset the counter

For setting the counter

Solution:

Special agent Kevin's hunt for the terrorist led to a bomb that was set to explode in 30 seconds. The bomb can only be stopped if Kevin types in the definition of fan-in.

the number of outputs connected to a gate without any degradation in voltage levels

the number of inputs connected to a gate without any degradation in voltage levels

the number of inputs connected to a gate with degradation in voltage levels
