WebNov 1, 2024 · A real time-varying graph signal with the topology shown in Fig. 3 is estimated in Section 5.4. The graph signal in Fig. 3 represents hourly temperature recorded across the U.S. at 205 different locations [40]. We use geography-based graph generation with 8 nearest neighbors seen in [6] to form the topology shown in Fig. 3 with N = 205. Webfrequency and the phase information of a signal. The phase information the FFT yields is the phase relative to the start of the time-domain signal. For this reason, you must trigger from the same point in the signal to obtain consistent phase readings. A sine wave shows a phase of –90° at the sine wave frequency. A cosine shows a 0° phase.
