8.9 consider the design of an ofdm modulated signal. assume that the transmitter operates at a 10 mhz complex sample rate, and that the maximum expected delay spread is less than 1 s. (a) what is the complex nyquist sample period, ts (which is not the length of the ofdm symbol)? (b) to assure orthogonality, what is the minimum number of samples to use for the cyclic pre x? ((c) if the ofdm symbol has 100 subcarriers, what is the subcarrier spacing in frequency? (d) if the ofdm symbol has 100 subcarriers, how long in time is the ofdm symbol including the cyclic pre x determined previously?

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

m=-16

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
