what is the output in an RC coupled amplifier?is it Vcc-ic*rc where Vcc is the dc supply voltage or ic*rc?
is it ic*rc then why is it so?
isnt Vcc-ic*rc an ac signal,then how can the capacitor remove the dc shift in the output ?

 

The output will be AC. The signal is coupled into a resistance, usually refered to ground. The capacitor blocks DC, so the signal out will be an AC waveform with a magnitude approximately equal to the magnitude of the voltage swing at the collector of the output transistor. The voltage is affected by the RC time of the blocking (or coupling) capacitor and the resistance of the mext stage input, or load. The lower frequency components of the signal may be attenuated as the RC arrangement makes a high pass filter response.
