Adigital communication link carries binary-coded words representing samples of an input signalxa(t) = 3 cos(600πt) + 2 cos(1800πt).the link is operated at 10,000 bits/s and each input sample is quantized into 1024 different voltage levels. a) what are the sampling frequency and the folding frequency? b) what is the nyquist rate for the signal xa(t)? c) what are the frequencies in the resulting discrete-time signal x[n]? d) what is the resolution?

explanation:

so if you are under a school block you cant but it may also be do to you having to add it to your chrome book like an app like i did or its the wifi you have blocking it

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.
