A. Discharge Cycle 1In the first discharge cycle, P1 is set to high impedance, P2, P3, and P4 are set to low. For this condition all the three SPDT switches S1 , S2 , and S3 are set to position “0”. Hence diode D1 conducts (forward biased) and diode D2 is in the cutoff mode (reverse biased). Capacitor C now discharges through resistance RT1=Rx+Ros , where
