PLEASE, i dont know the basic difference between voltage amplifiers, power amplifiers, audio amplifiers, radio frequency amplifiers, small signal amplifiers, large signal amplifiers...:confused:
i am in my 3rd year in electrical electronics engr in school and we dont do (or i dont understand) many practical but what i am doing on my own is small transistor projects after getting components i can buy, so if you break down the words you use a little, i will greatly appreciate it. any suggestion is also appreciated:(

If your course Text covers this,read it!
If not,Google for all those things,

OR

Go to the local library & see if you can find a book on these subjects.

voltage amplifier: Vout = AvVin
power amplifier: Pout = ApPin
audio amplifier: signal in, signal out are audio frequencies 20hz-20khz
radio frequency amplifier: signal in, signal out are radio frequencies: > 20khz
small signal amplifier: abstraction of an amplifier where signal is sufficiently small that the transfer function (vout/vin) can be considered linear.
large signal amplifier: abstraction of an amplifier where signal is sufficiently large that the transfer function (vout/vin) can be considered nonlinear.
