Understanding AC Signals: Sine Waves, Amplitude, Frequency, and Phase
Generally, AC refers to sine waves. In this case, the signal can be described by the following equation: 𝐴 sin 𝜔𝑡 + 𝜑, where 𝐴 is the amplitude, 𝜔 the angular frequency, and 𝜑 the phase shift. 𝜔 = 2𝜋𝑓 = 2𝜋/𝑇, where 𝑓 and 𝑇 are the frequency and the period of the signal, respectively.
