Introduction to digital signal processing: Part 6 - Modulation and demodulationThis sixth and final instalment deals with the subject of modulation and demodulation. Amplitude modulated (AM) signals are most conveniently demodulated when their envelope is constructed, which is done by rectification of ...
Special should point out is the 80 s to the 90 s of the development of a set of high-speed multi-mode adaptive coded modulation demodulation technology and signal processing and signal detection technology rapid development, to todays satellite communications, mobile communications, digital HDTV ...
Use of multiple antennas in wireless links with appropriate space-time (ST) coding/modulation and demodulation/decoding is rapidly becoming the new frontier of wireless communications. In the past few years, the theory of ST wireless communications has grown so large. An attempt is made to provide...

So that leads to the reverse breakdown of the diode. In Varactor Circuit (Signals Demodulation) Varactor diodes are frequently employed in varactor circuits to achieve intelligent control, optimization, frequency modulation, and scanning oscillation of circuits. They are commonly used in microwave ...
