| Abstract: | The meanings of quieting tone and the difficulty of quieting in amplitude modula
tion(AM) audi
o communication are introduced.The intermediate frequency(IF) digital
demodulation theory and quieting
tone principle are discussed. An effective method of distinguishing AM modulati
on degree i
s adopted. How to make use of the method
to solve the quieting problem in application is illustrated with an example. |
