In this chapter we continue our introduction to circuit analysis by studying periodic functions in both the time and frequency domains. Any periodic function may be represented as the sum of an infinite number of sine and cosine functions which are harmonically related. The response of the linear network to the general periodic forcing function may be obtained by superposing the partial responses

我们每天都在使用 Fourier变换,比如移动电话,CD,DVD,jPEG

Appendix C Some Fourier transform pairs Note:

1. is absolutely summable, 2. has finite energy
