+//Given
+
+vI1=0;//voltage at base of transistor Q1 in volts
+vI2p=5D-3;//peak voltage at base of transistor Q2 in volts
+vI2w=0.2;//frequency of vI2 in hertz
+vICM_a=0;//input common mode voltage in volts
+vOCM_a=5;//output common mode voltage in volts
+vICM_b=-2D-3;//input common mode voltage in volts
+vOCM_b=5.01;//output common mode voltage in volts
+vICM_c=2D-3;//input common mode voltage in volts
+vOCM_c=4.99;//output common mode voltage in volts
+
+//Solution
+
+dvICMp=vI2p/2;//peak input common mode voltage in volts
