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?

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

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.

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.

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.
