Question $1$: Given Figure $1$ and Figure $2$ above answer the following questions $(5$ points each,

$25$ points total$)$:

How many bits can be represented in one symbol by Figure $1?$

How many bits can be represented in one symbol by Figure $2?$

What modulation scheme is used in a radio system which utilizes Figure $1?$

What modulation scheme is used in a radio system which utilizes Figure $2?$

Which modulation scheme uses more transmission power $($on average$)?$ Assume both

figures use the same scale. Explain your answer.

Assuming a robust radio system with the greatest signal$-$to$-$noise ratio $($AKA perfect

wireless channel$),$ which modulation scheme would most likely be used between Figure

$1$ and Figure $2?$ Assume the goal is to achieve the highest bits per second.
