voltage divider bias

[rLet]

the thing is that i dont really know how to start. i need to design
this small signal amplifier in a voltage divider biasing. im using a
bc547 transistor and with these i need to write a dicussion and show my
prof the load line of my circuit. is there anyone from the PHILS that
could help me. thanks!

The answer should be in your textbook. Pick a collector current (low for
small signal amplifier; one mA or so). Pick an emitter resistor that drops
about 10% of the supply voltage using your collector current. Make the
bottom base resistor 10 to 20 times larger and pick the other resistor to
set the base voltage at 0.7 volts above the emitter voltage. Pick a
collector resistor to drop half of the supply voltage.
