Q1:

The output voltage waveform of a CE amplifier is fed to a dc coupled CRO. The trace on the screen will be

A dc output voltage

B ac output voltage

C sum of dc and ac output voltage

D either (a) or (b)

ANS:C - sum of dc and ac output voltage

Due to direct coupling between output and CRO both dc and ac output voltage will appear on screen of CRO.
