Abstract
锛?/p>
In The high-frequency electronic circuit designing job, our group selected the
topic as amplitude modulation circuit (AM) and demodulation. In this course design
report, first explains the purpose, content and requirements of the curriculum design;
clarify the basic principles and methods of operation standard amplitude modulation
and demodulation, and also to illustrate the principles of the filter circuit. Then
describes the use of Matlab and other amplitude modulation, demodulation and filter
design program written, along with the carrier signal debugging output modulation
signal, AM modulated and demodulated signal waveform signal before and after
filtering, etc. map and spectrum, also attached a total power and average power ratio
of the total gain response and bilateral band filter. At the end of the report is to
analyze the individual results of this large operation, process reflection and summary.
Keywords: amplitude modulation, demodulation, Matlab simulation
