Choice of three different signal-band spectral analysis carried out, according to the characteristics of the design spectrum signals of three different digital filter, the signal will be three-way all the way signal synthesis, analysis of time-domain signal synthesis and frequency domain characteristics of signals and then synthetic through three digital filter designed to isolate the original three-way signal, the three-way analysis of time-domain signal waveform and spectrum, compared with the original signal on frequency division multiplexing features.
