Abstract
It is determined whether or not a passing cell is a cell to be measured. If yes, a signal synchronous with the passing cycle of the cell is generated by a synchronous signal generator. The synchronous signal is digitally processed by a digital signal processor. Thus, each parameter related to the number of passing cells is obtained by converting the analysis based on the time axis to the area analysis based on the frequency axis.
