Question

Q. "Phase relationship between input and output signals. When a.c. is fed to the input circuit.
its positive half cycle opposes the forward bias of emitter-base circuit."

What it is meant by above lines?

Answer 1

Dear Student,
It is a pnp transister so emitter is positive and base is at negative potential, hence
when we apply ac signal , in positive cycle base will be at positive and emitter at negative .
So applied ac signal for positive half opposes forward biasing of emitter-base
