Answer:
ASK
Explanation:
The correct answer is ASK which denotes Amplitude Shift Keying. This is essentially a type of amplitude modulation which represents the binary data that comes varied forms right in the amplitude of a signal.
Now the reason why It is the most susceptible technique to noise is due to the fact that between frequency, phase & amplitude, amplitude is the one that is most susceptible to being affected by noise when compared to the other two.
Answer:
69.54
Explanation:
A power ratio of 9000000:1 corresponds to 69.54 dB.
The calculation is presented below:
Formula for calculating Power ratio (db) = 10 * log [P(out)/P(in)]
Since the given ratio is 9000000:1, substituting in the formula gives us 10 * log (9000000/1)
Note that log 9000000 = 6.954
Therefore, 10 * log (9000000/1) = 69.54
Hence the required power ratio in db is 69.54 db.
Indentation and alignment are very noticeable on a printed page, so you will probably want to set the tab stops in your document precisely how you want them.
Answer:
Program Comments
Explanation:
program comments are explanations. They are not executable code and the can actually appear anywhere in your code. Their main function is code documentation for the future. In Java programming language for example three types of comments is used. These are
// Single line comments (This starts with two forward slashes
/* Multiple Line
comment
Style*/
The third is the javadoc that gives a description of a function. I looks like the multiple line but is has two asterics
/** This is javadoc
comment
style*/
