A certain band-limited periodic current has only three
Chapter 17, Problem 17.74(choose chapter or problem)
A certain band-limited periodic current has only three frequencies in its Fourier series representation: dc, 50 Hz, and 100 Hz. The current may be represented as 3 sin 200pt 4 cos 200pt A (a) Express i(t) in amplitude-phase form. (b) If i(t) flows through a resistor, how many watts of average power will be dissipated?
