Look at the signals in their data files “c” and “d”, which have been generated. These signals are generated in different ways, and have different characters. Make a report, of 500 to 800 words, using the text box within the “report_xx” file, covering the following aspects:
Describe the signals.
Explain what information can be gained from carrying out an fft on each signal.
In the case of the signals, "a" and "b", all the information needed to generate the signals is contained with the few parameters f, v and t obtained from the fft. This gives a powerful method for compressing the storage or transmission of the signals, as only these few parameters need to be stored or transmitted.
Is the same true for the signals “c” and ”d”, and if not, why not?
