摘要
The peak value hold circuit contains a peak value hold register (17) for holding an instantaneous peak value and an operation device (18) which compares the instantaneous peak vlaue with an input signal. The operation device performs an operation on th epeak value and input signal when the input signal is greater than the peak value so that the peak value is replaced in the hold register. ADVANTAGE - Suppresses effects of occurrence of one or more abnormal bits.
