wien bridge input impedance
Electrical Engineering Asked by wadafukou on November 15, 2020
I want to know the input impedance at transistor T1’s base.
1/Z=1/R4+1/R+1/Rin and Rin=beta(re+RE)
But how do I calculate RE ?
My guess : R3 is 0 because the wire at T1 collector is removed, thereby RE=Lp ?
Thanks
