S14-2 Exponential Fourier series f(t)=+ cosot+a2 cos 2ot+.] sinot+ b2 sin

14-4 Line spectrum A plot showing each of harmonic amplitudes in the wave is called the line spectrum

14-6 Effective values and power The effective or rms value of the function f(t) is

14-8 Definition of the Fourier transform The exponential form of the Fourier series

The two-sided or bilateral Laplace transform The one-sided Laplace transform or direct Laplace transform

15-4 Laplace transform of some simple time function 1. The unit step function

15-6 The partial-fraction-expansion method

We define transfer function H(s) as a ratio of the Laplace transform of system output (or response)(s) to the Laplace transform of the input(or forcing function)v(s) when all initial conditions are zero, then
