How to bias a transistor to make a basic amplifier?

[sukhoimg]

hello
i'am a beguiner in electronics and need to learn how to bias a transistor to make a basic amplifier ?
how to calculat the resistors ?
let's say i have an BC547 NPN transistor and i want to bias it in common emmiter mode what should i take in consideration (the load ...) ?
please help .

Do you want to bias it for a particular operating point or stability or both. If stability, do you want to stabilize against changes in Vcc, Icbo, Vbe changes with temperature, or β? We could write a book to answer your question. Can you be more definite about what you want?

the answer is in you hitting some basic electronic ckts book real hard with an unquenchable thirst of knowledge
