Answer and Explanation:
the electronic devices always have some noises present in the signal
there are some important considerations in optical fiber communications these are.
- the noise which is contributed by transmitter are electronic random noise, low frequency noise
- noise which is contributed by laser are relative intensity noise, mode partition noise, conversion of phase noise to amplitude noise.
- noise contributed by photo detector are quantum shot noise, shot noise from dark current, avalanche multiplication noise.
PRINCIPLE OF POPULATION INVERSION :
The principle of population inversion is defined as for production of high percentage of simulated emission for a laser beam the number of atoms in higher state should be greater than lower energy state
Deciliter = 1/10 of a liter
Milliliter = 1/1000 of a liter
So, there are 100 milliliters in one deciliter
If long sight means farsighted, then here's your answer:
Farsightedness is when the lens has difficulty focusing on nearby objects. Sufferers must squint to see the nearby objects. Reading, writing, and drawing for longer periods of time can cause eyestrain and headache.
Being farsighted can be corrected with prescription glasses or contact lenses or surgery.
<span>If the </span>base<span> has 6 sides, the </span>prism<span> will also have 6 </span>lateral faces. It will all depend how many sides the base has and the lateral face of the prism will equal to the number of sides of the base. In short, if the base<span> has 'x' sides, then the </span>prism<span> will </span>have<span> 'x' </span>lateral faces<span>.</span>
