Explain small signal model of transistor to a newcomer

Pandora charm australia cheap I am a little weak in analog circuits in which electronics is my subject(Architectural course).Transistor is much a pandora box to me.Last day i read a question pandora charms for sisters about how to use transistor as switch in this website.It made complete sense with me.That gave me confidence to transistors.I want learn deep about this now.Deep enough so that i can even do analysis myself without referring any college textbooks.So please explain me about transistor models in clear language.

I understand transistor is.What i dont know is mostly about its models for circuit design like hybrid model, small incite model etc.I dont exactly equations(I got books to make the).Tell something in plain terms.

These small signal models are important if you'd like to characterize the frequency response of whatever amplifier you end up building with these transistors.In a lot of utilities, it is inadequate numbers to just know the Cheap Pandora Beads gain for a given dc input.

Suppose i have built myself a common emitter amplifier out of a bjt when it comes to amplifying an audio signal.For instance i've added my decoupling and bypass capacitors and biasing circuit as well.How would i go about determining whether my amplifier ends up attenuating 15 khz signals?How would i determine if my signal output at 40 hz is sufficiently strong?With regards to amplifying audio, these frequencies are crucial to consider.

The gain is not uniform across all wavelengths and this is due to the inherent capacitance and resistances inside the bjt itself.Thus we need to construct these models that closely resembles the transistor's internals when it comes to performing circuit analysis on paper(Or perhaps in cad, circumstance tools allow)That will tell us if our amplifier design is towards our application or not.The parameters you speak of are usually given in the transistor's datasheet such that you can plug them in to one of the commonly accepted small signal models and perform your car finance car loans measurements.
