n = noise factor = .2 (correspond to SNR of -10dB for received signal)
sampfreq = sampling frequency = (20*(10 ^6)) Hz
The sampfreq value of 20*(10^6) Hz was given in"Computer-Based Exerciese for Signal Processing Using MATLAB"by Burrus [ et al.] as an example sampling frequency to use
The paramter"Time Delay"(i.e. TD) is the amount by which the user wants to shift his vector by (i.e. not units of time)
The max range that could be accounted for according to equations based in
"Approach for Range" module was 8190 meters (8.2 kilometers)
The starting value of the past two graphs are at n = 1
Analysis of results
Overall result of test cases given by a graph of the %error of the range approximation compared to"

Method of error calculation
The % error was calculated by first taking the returned value for range from our developed program and using that as an input to the"
radar "function from Burrus [ et al.]. The resulting waveform generated is then put through the same match filter as our simulated received wave. A comparison of the location of the 1st peaks is then done and the absolute value of the difference is taken. The value is then divided by the difference from the right most edge of"
radar "'s first chirp to the end of the signal.
Comment on % error
The % error increased in a direct proportional to however larger we made the new TD value. Thus, if a shift of TD=900 was applied, the % error was 9 times greater than in test case 5 ( TD = 100), it was in fact about 55.89%.

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

you have been hired as an espert witness in a court case involving an automobile accident. the accident involved car A of mass 1500kg which crashed into stationary car B of mass 1100kg. the driver of car A applied his brakes 15 m before he skidded and crashed into car B. after the collision, car A s
can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
