Dynamic Range, BJT transistors..

[sonaiko]

a fast question..
i have electronics exam next week, and i have this question..
identify the dynamic range??
what is the dynamic range :?: :?:
this is the first time i here about that!
it should be connected to Forward Active BJT transistors or the differential AMP!!
is that the range wer the Q point must be 1/2 of Vcc or what?
help plz..

Dynamic range is the difference between the lowest signal and the highest signal, so for an audio amplifier the lowest signal is that just above noise level, and the highest is that just before the onset of clipping.

I don't see any real relevance between those and dynamic range?. I also have no idea what a 'Forward Active BJT' is?.

FA BJT it is when the V betwen base and emitter is forward and 0.7 volts. and the collecter emeitter voltage is above 0.3V.
FA transistors r used as amplifiers.

thanx man. ur dynamic range answer is right! it is the effective value of the signal between the cuttoff and the noise of the signal...
