If those cosine wave spectral components continued their rotation by φ° we ... a discrete sequence of a 400 Hz sinusoid sampled at a 2 kHz sample rate. Figure 10. Spectrum of a signal with four ...

The frequency spectra of the signals are, however, often overlooked, especially if they're complex data patterns. Figure 2. A square wave's frequency spectrum consists of the fundamental frequency and ...
