Hi,
I can't figure out this problem... Please see the attachment. I'm not even sure whether the "true" statement is in fact true.
How do I go about solving this? I don't know whether the BJTs are in saturation or in the active region... so are they functioning as switches or what?
Surely, if Q1 turns ON, then 12V will appear across the 10k resistor, so Vout = 12V, not Vin?? But obviously the circuit is a kind of buffer, so the output should equal the input.
Please help me understand this cct!
Thanks
