If an audio signal is to be coded, either for compression or for digital transmission, it must undergo some form of quantization. Most often, a general technique known as vector quantization is employed for this task, but this technique must be tailored to the specific application so it will not be addressed here. In this assignment, we will observe the effect of uniformly quantizing the samples of two audio signals. a) Record your voice for 4 seconds and play it again using predefined MATLAB audio functions.
b) Use your Uquant function to quantize each of these signals to 7, 4, 2 and 1 bits/sample.
c) Listen to the original and quantized signals and answer the following questions using the comments in the same MATLAB file:
1- For each signal, describe the change in quality as the number of b/sample is reduced?
2- For each signal, is there a point at which the signal quality deteriorates drastically?
3- At what point (if any) does it become incomprehensible?
4- Which signal's quality deteriorates faster as the number of levels decreases?
5. Do you think 4 b/sample is acceptable for telephone systems? ... 2 b/sample?
d) Use subplot to plot in the same figure, the four quantized speech signals over the index range 7201:7400.

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

this happens because the number is known for scamming, they don't want it to me known as "scam likely." perhaps it's just a telemarketer. maybe it's an identity thief. it might even be a scam artist.  

either way, "scam likely" is probably not an old friend whose number you forgot that you saved. it's your wireless carrier's way of letting you know: answer at your own risk.

explanation:

to combat the seemingly rising epidemic of spam callers in the u.s., the nation's four major wireless carriers have been trying out new methods to reduce the number of unsolicited calls americans receive each day.

hope this . mark me brainliest.

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.
