Hi!
I have a bit of a problem with drawing the h parameter model of a voltage amplifier circuit. Schematics are in the attachment.
I've sketched h model, having in mind that hre~=0.
I know that if amplifier works in medium frequency range, C can be changed with a conductor because it's impedance is small.
But, where do I wire the Rb and Rl?
On their upper side, they are on Vcc potential. For signals, Vcc is bypassed to ground potential, therefore, on one side, Rb and Rl are on ground potential.
On their down side, Rb and Rl are on the same potential [or that is what I assume]. But, what potential?
Oh yaeh, problem is to find amplification given as vo/vi . I think I could do that by myself if only I could draw this h model.
Thank you for your time .
