    Discussion Questions: 1. The average time for the first harmonic was 7.61. The average time for the second harmonic was 3.44. The average time for the third harmonic was 2.41. The second harmonic was half (1/2) of the first and the third harmonic was a third (1/3) of the first. The relationship between the first harmonic of the coil and all the other harmonics is 1/n, where n is equivalent to the harmonic number. 2. As determined in the previous question, you can tell that you missed a harmonic by looking at the data. The observed times can be compared to determine the pattern 1/n. If the data does not follow this pattern, then you are able to tell which harmonic you missed. For example, if you have the first harmonic which is 21, and the third harmonic that is 7, one can interpret that the second harmonic is missing. This can be explained because 7 is 1/3 of 21 so, the second harmonic would be 14. Additionally, this process could be reversed, meaning if you have the second harmonic and require the first, one can double it to get an approximate value of the first harmonic. Additionally, from equation V= (N/t) x (2L/n) (the lower-case n is the harmonic number) one can also determine if they used the wrong harmonic number. If two harmonic numbers were mistaken, or one harmonic was forgotten then the speed would be drastically different from the other trials. 3. Done on Paper 4. Done on Paper. 5. The equation derived from part B doesn’t exactly match what happened in…

    Speed of Sound Abstract: We used a function generator to measure the hertz of the first harmonic with both ends open. We needed to execute multiple calculations to make sure at the end of the experiment it will equal to 343 hz. The measure moments that were given was the length of the tub and the diameter of the tub and the frequence of the function generator. We ended up getting 343 hz after calculating the displacement. Introduction: We are calculation a the standing waves in a pipe. To…

    Lower Sample Rate (22,050 SR, 128 kbps): 8/10 Since there was some slight static, we gave the sample a 8/10. This could have occurred because of the rustling of the recorders jacket. Since the phone was placed close to the recorder, this sound could have been easy to pick up by the recording device. I think if we were able to listen to the recording with headphones, it would have been a more accurate depiction of the quality. There was some breathing and wind sound that could be heard in the…

    Δfsw−coeff(푚,휃푣)=1−(1−Δfsw−nom(푚,휃푣))∗푘 (9) The coefficients are multiplied with the base switching frequency to provide the operating switching frequency of the inverter, as shown in Fig. 5. It should be noted that the base switching frequency magnitude does not depend on the sub-cycle current ripple variation and is typically adjusted based on operating current, speed and temperature of the traction drive [1]. SIMULATION RESULTS For the simulation study, a two-level inverter driving a…

    1. Explain the difference between periodic and aperiodic waveforms. What are the visual differences? What are the characteristic sonic qualities of each? (2 points) Answer: A periodic waveform has repeatable patterns. Also, periodic waveforms have a tone. Most musical instruments have repeating periodic waveform. The periodic waveforms can also be found in bird sound and human vocal voice. However, an aperiodic waveform dose not have a repeating waveform and tone, like noise, the engine…

    In normal mode, the oscilloscope only sweeps if the input signal reaches the set trigger point; otherwise (on an analog oscilloscope) the screen is blank or (on a digitizing oscilloscope) frozen on the last acquired waveform. Normal mode can be disorienting since you may not see the signal at first if the level control is not adjusted correctly. Auto mode causes the oscilloscope to sweep, even without a trigger. If no signal is present, a timer in the oscilloscope triggers the sweep. This…

    This case review involved a 19-year-old male football play who is currently a freshman in college. He came into the athletic training room complaining of right wrist pain. This athlete has had pain in this wrist for a couple of mouths and had only every taped the wrist two weeks prior to coming into the athletic training room for his first treatment. Even before coming in, he was able to do every drill or exercise at practice to completion. He only reported feeling pain during practice when he…
