Answer:  None; all will be recoverable

Explanation:

If a signal (band-limited) is sampled at regular intervals, it could be recoverable or not, based on the number of samples taken.

Let's assume that we want to take samples of a simple sinusoid; If we take more than two samples during a signal cycle, the original waveform will be able to be reconstructed, just passing the sampled waveform through a low-pass filter.

In the more general case in which the signal occupies a frequency spectrum, if the sample frequency is greater than the double of the highest frequency in the spectrum, the signal can be retrieved completely, according to the  Nyquist Theorem.

In this case , as the highest frequency is 145 Hz, it would be enough  to take samples at a rate greater than 290 Hz; As the sample rate is 295 Hz, all the signal can be recovered, at least, using an ideal "brickwall" low-pass filter.

Murljashka [212]

Answer:

<em>SQL Query</em>

///////////////////////////////////////////////////////////////////////////////////////////////////

select Genre_Name, Number_Purchased from Genre

INNER JOIN Tracks on Genre.Genre_Name = Tracks.Genre_Name

WHERE Number_Purchased >= 10 AND Tracks.price >= 1

ORDER BY Number_Purchased ASC;

Explanation:

First off, I selected the required columns from <em>Genre</em> Table.

Then I inner joined <em>Genre</em> table with <em>Tracks</em> table, to get the <em>price</em> of tracks of the corresponding Genres.

Then the required Where conditions are written, which includes one from the <em>Tracks</em> table.

Finally, the Order by statement is written by <em>Number_Purchased</em> column in ascending (ASC) order.
