Embodiment Construction
[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0028] Such as figure 1 Shown, the inventive method has adopted following steps:
[0029] The first step is to condition and shape the signal under test;
[0030] In the second step, the conditioned signal is divided into two paths, one path enters the digital acquisition system, and the other path is used to generate tracking trigger signals;
[0031] The third step is to collect the signal under the control of the tracking trigger signal;
[0032] The fourth step is to analyze and process the collected signals and detect weak low frequency signals from the unknown strong frequency conversion signals.
[0033] Such as figure 2 As shown, the first step to the third step of the method of the present invention are realized by a signal acquisition circuit: the signal acquisition circuit is composed of a power supply unit, an emitter follower u...
