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.
