I need a Conclution written in third person for this Data Analysis.
Analysis of Results
During the study of pulse waveforms, the duty cycle, amplitude, pulse width and period of several wave types was analyzed. Different frequencies were used between each part of the lab assignment. If anything leads to a higher probability of error, it would have to be method of measurement employed in the lab assignment. Since the oscilloscope is the main equipment used to measure amplitude, pulse width and period, and this machine not giving a digital readout of the values, having to eyeball them will inevitably lead to errors of various decimal places.
Higher frequencies equate to smaller pulse widths, while higher voltages lead to waveforms with higher amplitudes.
When a positive offset is given to the square wave, the average value is positive, while a negative offset yields a negative average value.
The other thing that is severely impacted by the offsets is the Amplitude of the waveform, with the negative offset yielding an amplitude close to zero.
The oscilloscope can be used to measure frequency, amplitude, pulse width and period, although very inaccurately, since the reading is analog and not digital.
When the ad/dc coupling is switched back and forth from ac to dc and back, the wave becomes symmetrical when it’s set to dc. This is because it adds the dc component to the wave, meaning that it gets its negative side, unlike when it’s set to ac coupling, which only shows the positive side.
Explanation / Answer
conclusions :
1. This Data analysis contains gross errors because the measurement involves humans.
2.The High frequency and High Amplitude waveforms offsets can be read in the positive side but difficult to recognise in the negeative side because the amplitude is very close to zero
3. The switching of coupling from AC to DC and viceversa may introduce errors
suggestion
1. A through analysis of the data needs a digital equipment
