ABSTRACT:
A method and apparatus for detecting a peak value of a waveform signal continuously inputted during a predetermined time period. The method includes the steps of: sequentially sampling the waveform signal continuously inputted during the predetermined time period and converting respective sampled values into consecutive trains of digital data of n-bit (n is an integer of 2 or larger); dividing each train of the converted n-bit digital data at least into two groups and obtaining at least an upper sub-data set and a lower sub-data set; detecting an upper sub-data set having a peak value from all the upper sub-data sets corresponding to the waveform signal continuously inputted during the predetermined time period; detecting a lower sub-data set having a peak value from at least one lower sub-data set corresponding to at least one detected upper sub-data set having the peak value; and outputting digital data of the detected upper and lower sub-data sets, as digital data having a peak value of the waveform signal continuously inputted during the predetermined time period.
