What is the resolution of an analog-to-digital converter with a word length of 12 bits and an analogue signal input range of 100
Elena L [17]

Answer:

The resolution of an analog-to-digital converter is 24.41 mV

Explanation:

Resolution of an analog-to-digital  = (analogue signal input range)/2ⁿ

where;

n is the number or length of bit, and in this question it is given as 12

Also, the analogue signal input range is 100V

Resolution of an analog-to-digital  = 100V/2¹²

2¹² = 4096

Resolution of an analog-to-digital  = 100V/4096

Resolution of an analog-to-digital  = 0.02441 V = 24.41 mV

Therefore, the resolution of an analog-to-digital converter is 24.41 mV

sp2606 [1]

Answer:

Concrete

Explanation:

The speed at which sound propagates is medium dependent. As one of the forms of mechanical waves, sound requires a material medium for propagation from place to place.

  • Sound travels with the least speed in air because air particles are far apart and they are randomized.
  • Sound travels with the greatest speed in solids. Concrete is the only solid material given in the choice.

The speed of sound increases from air to liquid and to solid.
