北京航空航天大学出版的matlab从零进阶的原程序代码第1章案例21.3源代码(Beijing University of Aeronautics and Astronautics from zero Advanced matlab published the original program code in Chapter 1 Case 21.3 source code)

making exponential signal with matlab In communications, the purpose of using exponential signals instead of sinosuid ones is to use both halves of signal spectrum(Negative and Positive sides of spectrum). For example an FSK signal can not simply downconverted to DC. because its spectrum is not symmetric around its center frequency, so you should downconvert it with exponential signal( the idea of using I and Q downconverter).
