Electronic component.The effect of A/D conversions is that Time Continuous, amplitude also continuous analog quantity are converted to time discrete, amplitude
Discrete digital signal, therefore, A/D conversions generally will be through 4 over sampling, holding, quantization and coding processes.
The resolution ratio of analog-digital converter refers to that, for the analog signal in allowable range, it can export discrete digital
The number of signal value.
FPGA (Field-Programmable Gate Array), i.e. field programmable gate array, it is as special
A kind of semi-custom circuit in the field integrated circuit (ASIC) and occur, not only solved the deficiency of custom circuit, but also overcome
The limited disadvantage of original programming device gate circuit number.

This method is current main stream approach, but the energy that can not differentiate each particle can only obtain a large amount of particles at the time of appearance
Average effect, the information that can retain is very limited, constrains the development of modern high energy nuclear physics.
Existing main problem is as follows：
1, the analog-to-digital conversion rate of the analog-digital converter of general digital multiple tracks is difficult to improve without limitation, is generally up to no more than
GHz or so, therefore when the arrival time of particle close to nanosecond, each particle can not be told.
2, in order to accurately analyze the energy for measuring each particle, it is necessary to which exhibition is formed in the signal to preceding putting output
Width, to can get excellent impulse amplitude measurement effect.And under high count rate, shape stretcher pulse all accumulation and
Each pulse can not be differentiated.
