#Repeated example with silicon diode
import math
#initialization of variables
v=4 #v in Volt
Vi=[16,-16] #peak voltage in Volt
VT=0.7 #thresold voltage
#calculation
print "+16V dc supply is pressuring the diode to stay in the short circuit state"
print "But for any Vi < v,it will result in short circuted diode"
print "But for any Vi > v,it will result in open circuted diode"
print "If the diode voltage is 0.7V"
v = v-VT
print "resulting battery input voltage = %.1fV" %(v)
print "For open circuit state"

print "V0 =%dV " %(V0)
print "for the negative region of the input signal,the diode will be in the 'on' state"
if [Vi[1]==-16]:
V0 = v
print "V0 = %.2fV" %(V0)
