Explain Nyquist Theorem?

Answers

Final answer:

The Nyquist Theorem is a principle in digital communications specifying that a signal must be sampled at least twice its highest frequency in order to accurately reproduce the original analog signal. An example is digitizing an audio signal with a highest frequency of 20 kHz, which needs to be sampled at a minimum rate of 40 kHz.

Explanation:

The Nyquist Theorem, also known as Nyquist-Shannon sampling theorem, is a principle that engineers follow when digitizing analog signals. This theorem is fundamental for understanding how digital audio technology works. It states that a signal must be sampled at least twice its highest frequency in order to accurately reproduce the original analog signal. In simpler terms, it's a guideline for converting a continuous analog wave into a series of discrete digital samples.

Let's take an example. Suppose you have an audio signal with a maximum frequency of 20 kHz. According to the Nyquist Theorem, you need to sample that audio signal at a rate of at least 2 (20 kHz) = 40 kHz to accurately digitize it. This is why the standard sample rate for audio CDs is 44.1 kHz (slightly higher than the 40 kHz rate determined by the Nyquist Theorem).

Which phrase best describes wave motion

Answers

Hi!
I don't know your options, but i can describe the wave motion for you:

wave motion is energy transfer through space that proceeds in regular variations (such as vibration),- we say that it's an oscillation because of the regular variations. These variations have specific characteristics, such as frequency or length.

Harnessing the sun's energy to produce heat or electricity is _____.. A. non-polluting . B.inexpensive . C. possible only in coastal areas. D. a mojor source of air pollution.

Answers

harnessing the sun's energy to produce heat or electricity is : A. Non - Polluting

This energy generating method will cause no dangerous emission for environment (unlike the one that came from fossil fuel), but the energy that produced from the sun tend to be more expensive so it's still not widely used

hope this helps
Harnessing the sun's energy to produce heat or electricity is _____.

Answer: Out of all the options shown above the one that completes the statement above and makes it true is answer choice A. non-polluting. This is called solar power which is also a renewable resource.

I hope it helps, Regards.

Traditional explosives use the energy released by chemical reactions. Nuclear weapons use the energy released by nuclear reactions. Why are nuclear weapons much more destructive than traditional explosives? Question 16 options: A. Chemical reactions can release much more energy than nuclear reactions B. Chemical reactions always use more energy than they release Nuclear weapons always contain more chemicals than traditional explosive C. Chemical reactions always release more energy than they use D. Nuclear reactions can release much more energy than chemical reactions

Answers

I believe the correct answer from the choices listed above is option D. Nuclear weapons are much more destructive than traditional explosives because nuclear reactions can release much more energy than chemical reactions. Hope this answers the question.

Answer: The correct answer is option D.

Explanation:

Chemical reactions are defined as the reactions in which rearrangement of one or more substances gets converted to one or more different substances known as products. Energy is released in the reactions where energy of products is less than the energy of the reactants.

Nuclear reactions are the reactions in which atomic nucleus undergoes change and releases a huge amount of energy in the process. There are two types of nuclear reactions: Nuclear fusion and nuclear fission. Both the nuclear reactions releases a huge amount of energy.

From the given information above, we conclude that the correct option is Option D.
