This chapter considers stable circuits, although the techniques are developed so that they apply to other situations. Sinusoidal signals are important because they are self-reproducing functions of linear time-invariant circuits. The importance of the Fourier series representations is that a circuit having periodic signals can always be considered to be processing these signals as exponential signals, which are usually self-reproducing signals for the system, making the design or analysis easy. First-order circuits are fundamental to the design of circuits because higher order circuits can be considered to be constructed of them. Because real transfer functions can be factored into real second-order transfer functions, second-order circuits are probably the most important circuits available; most designs are based upon them. Because information into and out of a circuit is carried via time domain signals some of the basic signals used in continuous time circuits.
