In this lab we learned how to familiarize the vibrations and signals that are basically can be found everywhere in life like The vibrations of the string of a guitar for example produces sound, pressure waves in the air. This lab was mainly about learning how to use the oscilloscope step-by-step and learning how it functions. Throughout this experiment we investigated two types of signals, which are the periodic signals and the transient signals.
The periodic signal is the sound of a vibrating string produces a periodic voltage in the microphone.If the time period of the signal is T then the waveform repeats every period T. The periodic signal is characterized by its time period T or frequency. Moreover, the transient signal is the signal when there may be long periods of time when nothing happens and then suddenly you get activity for a moment and then nothing again. An example for a transient signal can be a heart beat pulse, or it can be an earthquake monitor. The equipment used for this lab are the oscilloscope and the signal generator.
The first part of this lab was about the XY mode of operation, and measuring DC static voltage. The first step was to turn on the scope and wait for it to boot up, then, without attaching any wires, we set the scope to XY mode and set both CH1 and CH2 to 1 Volt/Div. After that, we connect the battery to CH1 input, and we set the battery to 1.5 Volts. We noticed that the yellow dot on the screen would jump 1.5 Volt to the right along the x-axis. We then do the same thing but with CH2, and we notice that the yellow dot jumps up 1.5 Volt on the y-axis. If we connect it to both CH1 and CH2, we will notice that the yellow dot would jump up 1.5 Volt and go to the right 1.5 Volt also.
For the second part of this lab, we dealt with signal generator and using it as an input for CH 2 of our oscilloscope. After following the instructions provided in the manual we first can notice a sine wave on the scope. We then change the Time/Div on the scope to 1 second. We then moved on to change the waves into triangular and square waveforms. After we finished this experiment we became more familiar with the most important settings of the oscilloscope and signal generator.
This lab taught us how to use the oscilloscope and learn how it functions. The scope mainly shows two types of signals, which are periodic signals and transient signals, which were discussed in the introduction. The oscilloscope is considered as the most useful instrument available or testing circuits because it allows you to seethe signals at different points in the circuit as a function of time. The best way of investigating an electronic system is to monitor signals at the input and output of each system block.
Hypothesis contrary to fact is defined by Bo Bennett on his website “Logically Fallacious” as offering a poorly supported claim about what might have happened in the past or future, if circumstances or conditions were different. The fallacy also entails treating future hypothetical situations as if they are fact. An example of this from the video is when Max claims that Polly would have never learned her fallacies if he had never come along. Max’s claim is poorly supported because it is very possible that Polly could have learned fallacies from someone else if Max had never come along. Different circumstances would have had different outcomes.
“Love is a Fallacy” uses logical and real-life scenarios to make its point. Often times we under estimate other people and in this video we see that Max under estimates Polly. Polly, though her mannerisms come off very unintelligent, is in fact smarter than she portrays. This video puts the viewer in a very common situation for our age. The strategies and assumptions that Max uses such as saying they are a good match, that he loves her and that she owes him, are common relationship strategies among today’s youth. The fact that Max teaches Polly the fallacies and then uses them also proves that even though we may have the understanding of fallacies, we are still capable of using them in an argument.
The title “Love is a Fallacy” is bias and is not so black and white. It is simply an outlook or opinion stated to sway the viewers position. We can not conclude that this statement is either reliable or true. Polly’s decision to go steady with Petey Bellows is very ionic. Max puts much effort into getting Polly as his girlfriend and it ends up working against him. We see in this situation that often times fallacies are used in a relationship but that does not necessarily get the relationship to move forward. While Petey and Polly may have started dating because Polly made a promise to Petey, their relationship was not based on any fallacies. Instead it was based on his raccoon coat and the mutual decision between the two. Max’s effort to train Polly to be intelligent so he could have an intelligent beautiful wife as a lawyer failed.
After watching the video and hearing the fallacies that Polly was calling out on Max, it made wonder how many times people actually believe fallacies like that. The things Max was saying were things that we hear in society all the time. Do you think that if more people saw this video or understood fallacies better that they would have a different reaction to the relationship fallacies that they encountered?
