Best ResponseYou've already chosen the best response.0so i know that a Si diode has a 0.7 V drop and a Ge diode has a 0.3V drop. so i'm confused as to what happens afterwards. at the 2kOhm resistor.

Best ResponseYou've already chosen the best response.1Can't do the first for lack of input Assuming Si on voltage or .7 volts ID = (10  .7)/(1.2 +4.7) mA = 1.58 mA If this is sufficient for ID on then Vo = 1.58X4.7 V = 7.45 V

Best ResponseYou've already chosen the best response.0whoops. the first one has an input of 12V

Best ResponseYou've already chosen the best response.0so then Vo for the first one would end up being about 9.2V?

Best ResponseYou've already chosen the best response.1Yes, apparantly you got the idea, more accuarate analysis would entail using the Ideal diode with the specification of diode. Could be tricky but necessary if one is to have a signal input as well as DC, you will need to fine the diode signal resistance. This is used as a demodulator ciruit generally for Ampitude Modulation, AM
