  • Page 69 7.HOLD FUNCTIONS The Hold Function in General The delay times of the judging signal and the H/E signal do not include a ● delay time of the analog circuit (low-pass filter). Also, the delay times are calculated without the digital filter. Since the judging signal and the H/E signal are generated for the value produced through the analog and digital filters, transmission of the signals becomes slower and the delay of each output signal increases with enhancement of the filters.
