Introduce a while loop $($Right click on the Block diagram and choose "Structure", "While loop"$).$

Introduce a button for stopping the while loop if needed $($Right click on the red button in the lower right corner and select create control$).$

Generate and display a signal $($sine wave$).$ Call it Signal A $($Same as in Lab $1).$ Set the number of samples to $100$ and uncheck the automatic box. Select $1000$ samples per second. Set the frequency to $10Hz.$

Introduce a sample compression block $($Right click on the Block diagram, find search. Click on "search" and type "compression" to find the block "Sample Compression".$)$ and select to display the mean output of the input signal. $($use reduction factor of $10)$

Introduce a switch and connect it to the Enable port of the sample compression to be able to turn on and off the sample compression block. $($Right click on front panel and choose "Boolean", "Vertical toggle switch" or another switch. Go back to block diagram and draw a line between the switch and "Enable" of the compression block$)$

Send the mean of Signal A to an Express table. $($Right click on front panel and choose "List, Table & Tree", $"$Ex Table"$)$

Introduce 'time delay' to control the display rate of output. $($Use delay as $0\mathrm{.}05sec.$ Same as in Lab $1)$

Generate another signal by modifying the original input signal using the arithmetic expression $(2**si{n}^{2}t).($Right click on the Block diagram, find search. Click on "search" and type "expression" to find the block "Formula $$ Arithmetic & Comparison $>>".$ Then define the original sine wave as $"$X$1"$ and input $"2**x1**x1")$ Display this new signal, calling it Signal B$,$ on your graph along with Signal A and the mean of Signal A $($Same as in Lab $1,$ remember to turn the switch on$).$ How does the frequency of signal A differ from the signal B$?$ Why?

Change the sample compression factor to $100.$ What happens to the mean of Signal A$?$ Why? $($Tips: Set compression factor to $50,25$ and check the results.$)$
