Homework Help: H-parameter BJT (transistor)

  1. Dec 5, 2004 #1
    Hi, can anyone please look at the attached file and try to ans. the 4th question.

    there i can't figure out the "role" of two resistors Rb1 and Rb2 and the capacitor C2.

    Here's what I figured:

    The ground point with the Capacitor C2 makes the resistors R1 and R2 in parallel.
    And the current Ic is divided into two - Ic = which flows through the transistor and the current Ic' = which flows through the resistor&capacitor configuration.

    This Ic' is further divided into Ic1' and Ic2' .

    Ic1' = going to ground through capacitor
    Ic2' = going towards the base through Resistor Rb1.

    Please ans. if this is correct and please try to provide some explanation as to what happens.

    Thanks a lot for you generous help!!!

    Waiting for you reply! (eagerly).
