Ephraim... I posted this to check if there are any difficulties in posting your diagrams.It is possible to post .DOC files but you have to download them rather than opening them directly, which is a minor inconvenience. Just use the "Attach files" button in the question posting screen. You could also post an image file (JPG/PNG/BMP) and/or a PDF this way.I would reword as follows:"The voltage divider centre point holds the base at a DC potential around 0.6V above the desired emitter voltage for the BC108 transistor (You should give this voltage)"
"The collector resistor sets a limit of the collector current and also the loading impedance for the transistor to develop a voltage swing across. It also sets the load line output swing to the minimum and maximum values; it sets the maximum power dissipated in the collector of the transistor."That's a little cumbersome, but basically right.
"the 20kΩ resistor is use to take out DC from the capacitor,"
It is a load for the circuit for test purposes (it may not be needed when a real load (maybe another amplifier stage) is connected. It does not "take out" DC from the cap, but provides a discharge path for the capacitor so it does not get a permanent charge. the voltage divider centre pointholds the base at a DC potential just above the required base emitterjunction bias voltage of 0.6 or 0.7 for the BC108 transistor the voltage divider centre pointholds the base at a DC potential just above the required base emitterjunction bias voltage of 0.6 or 0.7 for the BC108 transistor
