Three amplifiers X, Y and Z are connected in series. If the voltage gains of X, Y and Z are 10, 20 and 30 respectively and the input signal is 1 m V peak value then what is the output signal voltage (peak value) if dc supply voltage is 10 V?
Text Solution
Verified by ExpertsThe correct answer is:
C
For cascaded amplifiers, total voltage gain is:
Input signal:
Expected output:
Since the DC supply voltage is 10 V , an output of 6 V is possible (no clipping).
