Signal distribution circuit and signal distribution circuit system

A signal distribution circuit system, comprising:

• a signal source configured to provide an initial broadband signal;
• a clock signal circuit coupled to the signal source and configured to control distribution of the initial broadband signal,
• a signal distribution circuit coupled to the clock signal circuit and configured to distribute the initial broadband signal, wherein the signal distribution circuit comprises:
• an equalization circuit configured to:
• collect the initial broadband signal;
• perform amplitude attenuation process on the initial broadband signal to obtain a first-stage broadband signal;
• and
• transmit the first-stage broadband signal,
• a signal distributor coupled to the equalization circuit and configured to:
• receive the first-stage broadband signal;
• distribute the first-stage broadband signal to obtain a plurality of same second-stage broadband signals;
• and
• transmit the same second-stage broadband signals
• an operational amplifying circuit coupled to the signal distributor and configured to:
• receive the same second-stage broadband signals;
• perform amplification process on a second-stage broadband signal of the second-stage broadband signals to obtain a third-stage broadband signal;
• and
• transmit the third-stage broadband signal;
• a feedback circuit coupled to the operational amplifying circuit and configured to:
• receive the third-stage broadband signal;
• and
• feedback the third-stage broadband signal, and
• a time sequence circuit coupled to the operational amplifying circuit and configured to:
• receive the third-stage broadband signal;
• adjust an amplification gain of the third-stage broadband signal;
• and
• transmit the adjusted third-stage broadband signal to a sub analog to digital converter array, wherein the sub analog to digital converter array is coupled to the signal distribution circuit and configured to convert the adjusted third-stage broadband signal from an analog signal into a digital signal.
