Signals piled up so far have been removed
from measurements by the pileup reject functionor have been used as error signals as they arewithout rejecting. The reason why this pile up
signal was processed and not reused was thatthe load on the computer to be obtained
analytically became too high and could not beprocessed in real time.
We have developed a hardware processor that
separates pileups in Real time.

New Pileup Separator Processor
The piled up signal is separated by thenonlinear least squares method.
The nonlinear least squares method is one of
the curve fitting methods for observation dataand is a nonlinear model function extension of
the least squares method.

For the judgment of the error between the fitted
waveform and the original waveform,the χ 2 evaluation function is used.
This 𝑦𝑖 is observation data.
