I am studying DFT of sinusoids, and my professor gave me this signal.
- Sinusoid Frequency: 100Hz
- Number of Samples: 512
- Sampling Rate: 8 kHz
I was expecting a single peak initially since the signal is only composed of a single frequency but from my understanding of the DFT, it mirrors the positive and negative values from the Nyquist rate which is 4kHz hence resulting to the two peaks. My professor then asks to 'correct' the peaks by modifying the parameters of the sinusoid. I am just confused as from what I understand the resulting peaks are correct.
