hi.
in my viva for pnp transistor- common base n common emitter input n output characterisitics, my sir asked me to get impedance for common base , common emitter n common collector. actually i didnt get his question properly. can anybody help me out with it or anythn relevant..??

 

viva? That didn't come across. You're wanting how to figure out the impedance of 3 different transistor circuits?

 

yes. m tryn to figure out the impedance of the above three circuits
