Lab report paraphrasing - Essay Example According to Experiment 1 observations, the T value of the signal when increased to 2 seconds from 0.5 seconds in 0.5 increments, the Fourier Transform accuracy also rises. Consequently, it is also evident that when the value of T is 0.5 seconds, the graph appears exceptionally different from the other 3 graphs since the period is not a big number to show the 2 tasks. These roles are actually the ones indicated on with line with the other one being made from the size of the troughs and peaks. This can clearly be seen when T=2 seconds in the graph in experiment 1. A correct value could not be displayed by the power spectrum because T value was too tiny. As illustrated, whenever the value of T rises, the power spectrum begins to exhibit the 2 co-sinusoids. When the experiment is over, it becomes clear that the magnitude of code required to solve the FFT is much shorter and simpler than the substitute DFT code. The other point to put into consideration would be the results obtained in section 3 of experiment 2.Thus, these results showed the time consumed to determine the DFT as well as the FFT, something that demonstrates that the FFT is quicker and realistic for determining the Fourier Transform. Consequently, FFT can be utilised in different methods through the entire electrical engineering comprising of researching on audio waves as well as the technique involving the audio signals, especially in recognition of pattern in instances where an engineer is searching for definite similarities or points, in addition to medical imagery like MRI scans etc. The above are just a few of numerous uses that electrical engineers are provided for by FFT at
