Embodiment Construction
[0031] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0032] to combine figure 1 As shown, a device for effectively suppressing the generation of stray broadband signals includes a power supply noise acquisition circuit 1 , a differential amplifier circuit 2 and an automatic tuning circuit 3 . Wherein, the output terminal of the power noise acquisition circuit 1 is connected to the input terminal of the differential amplifier circuit 2 , and the output terminal of the differential amplifier circuit 2 is connected to the input terminal of the automatic tuning circuit 3 .
[0033] The direction of the signal flow in the above device is:
[0034] After the power supply noise acquisition circuit 1 collects the power supply noise of the signal emitted by the signal transmitting device, it feeds back to the differential amplifier circuit 2 to suppress the power supply noise, and the suppressed signal is...
