What do you know so far for how to bias a Common-Emitter (CE) BJT voltage amplification stage? Do you understand how to do the basic biasing, and are asking where the bandwidth portion of the question comes in? Or are you not familiar with BJT biasing at all?
If it's just the bandwidth part of the question, you have an input signal coupling capacitor, and the bias circuit & BJT together present an input impedance. What kind of filter does that form for input signals coupled to the input capacitor?
Thats the whole question. I see theres a potential divider to find the values of resistance for Rb1 and Rb2, what i dont know know is what it means to "bias the amplifier". Im very unfamiliar with transistor circuits know only the very basics, the collector the base the emittor. Know that Vemitter = Vbase -0.6volts, and that its assumed that Ic = Ie as some rules of transisotrs.
From some notes iv got "Want Vcollector = 0.5 (Vin)" , is that whats needed to "bias the amplifier" ? if so i think can do it using those transistor rules and the fact theres a potential divider.
