The Research of Wrap Demodulation in Digital AM Broadcasting System
Cheng Jixing · Electronic Engineer · 2006
In this paper we introduce the demodulation method of digital AM broadcasting at first,and then give out two arithmetics: FFT and DCT.We discuss the principles of two arithmetics and their principles in demodulation of digital AM.Lastly we actualize this system' wrap demodulation in FFT and DCT arithmetics,and compare their performance of two methods.
