... X)dX. (13.110) Jo Jo We change the limits for two reasons. First, for physically realizable circuits, h(t) is zero for t < 0. In other words, there can be no impulse response before an ... -z = -2. 2a 1H 0.1 F The Location of Poles and Zeros of H(s) For linear lumped-parameter circuits, H(s) is always a rational function of s. Complex poles and zeros always appear in conjugat...

... responses of circuits, it may help to follow these steps: 1. Identify the variable of interest for the circuit. For RC circuits, it is most convenient to choose the capacitive voltage; for RL circuits, ... the same form (compare Eq. 7.48 and Eq. 7.50). To generalize the solution of these four possible circuits, we let x(t) represent the unknown quantity, giving x(t) four possibl...

... providing electric power in our homes, schools, and businesses. One common class of electrical devices is heaters, which transform electric energy into thermal energy. Examples include electric ... transformation of energy from electric to nonelectric form. In a purely capacitive circuit, the power is continually exchanged between the source driving the circuit and the electric...
