AC Sources

AC Circuits. AC Sources. Often, electrical signals look like sines or cosines AC power, Radio/TV signals, Audio Sine and cosine look nearly identical They are related by a phase shift Cosine wave is advanced by ?/2 (90 degrees) compared to sine We will always treat source as sine wave.

AC Signals

AC Signals. An ideal generator produces an induced emf that oscillates. Sine or cosine wave The oscillation is characterized by its period. The inverse of the period is the frequency. f = 1/ T Cycles per sec, or Hz Angular frequency in radians. 1 period = T. Sinusoidal Signal. e 0. t.
