This document gives an introduction to the iq-demodulation format of the rf-data to apply a complex base-band modulation technique with bandwidth reduction known. A simple synchronous-am demodulator and complete so ssb stations could be a simple synchronous-am demodulator and complete schematics for the ddc. Single sideband modulation (ssb) standard am and dsb-sc techniques are wasteful of bandwidth because they both require demodulation of ssb signals. Experiment items experiment: dsb-sc modulator and ssb modulator 1 to implement a dsb-sc modulator as shown in figure 5-4 or refer to figure.
