change the quantity exceeds the signal level Vr. Only when the peak is greater than Vr when (Vr F7.0V), the output of the diode D1 can be rectified positive peaks Q1. The resulting output filters Cx and Rx. Rx control the charging time constant or time out. Charging and discharging are required to use Cx.
