In Matlab command, load the data file KTXSignal`. Check the data variable. The sampling rate of the signal is 100 samples/sec.
>> load KTXSignal
1. Perform DFT for the KTXSignal using `FFT`. Plot the spectrum magnitude for KTXSignal. Since the DFT is discrete, you should use the plot function stem.
>> stem(abs(FFT(KTXSignal)))
2. Plot the spectrum magnitude along the normalized frequency .
>> stem(, abs(FFT(KTXSignal)))
3. Plot the spectrum magnitude along the normalized actual frequency `f`.
>> stem(f, abs(FFT(KTXSignal)))
4. Determine the signal power at the frequency range . (* The equation for the signal power is .*)
