A) \[30\,\,dB\]
B) \[60\,\,dB\]
C) \[3\,\,dB\]
D) \[20\,\,dB\]
Correct Answer: A
Solution :
Voltage gain,\[{{A}_{v}}=1000\] In\[dB\], voltage gain \[A=10{{\log }_{10}}1000\,\,dB\] \[=(10\times 3){{\log }_{10}}10\,\,dB\] \[=30\,\,dB\] \[(\because \,\,{{\log }_{10}}10=1)\]You need to login to perform this action.
