Why is voltage divider network of BJT so broadly used in frequency response compared to other networks?
Why aren't other networks much discussed in textbooks for frequency response?

As this is in the homework section, we can't just provide answers.

That being said, there is rarely exactly one solution for any problem.

We don't quite know what you mean. Post a circuit diagram and rephrase your question. What do you mean by other networks?

 

Voltage dividers are used in all sorts of networks.

by other networks i mean fixed bias,emitter bias etc aren't used for frequency response but voltage divider is used..why is that?

that i know but why are they preferred for frequency response but not other networks like fixed bias,emitter bias etc?

 

An exact answer to a vague question?

 

If you have a specific schematic you can provide showing a BJT being used as use suggest, that might be helpful. make sure you're not just making an assumption. Also, be aware that manufacturers frequently build circuits that are cost-based. BJTs are really cheap.

I think you are mistaken. Both voltage divider base bias and emitter bias are commonly used together.

 

If there exists an answer, it may be related to the stability of voltage divider bias with respect to other factors which affect the gain of a circuit.

Sorry but your question is way too inexact to give an exact answer.

 

Here we specialise in vague answers to exact questions. . . .

Hello,

If you are talking about a resistive voltage divider then that usually is not considered to affect the frequency response, except maybe indirectly. It would only affect it if it worked into some other frequency reactive component like a capacitor or inductor.

Because of the vagueness of your question you should post a schematic, then give your best idea of why it affects the frequency.

 

In general, frequency is not a deciding factor in Resistor networks. Because Resistor values do not change with frequency. Resistors are not frequency sensitive. This is in general usage over a wide frequency range - up to a few hundred Kilo Hertz.
