Explanation: The differential amplifier offers best immunity to induced noise because, the ratio of the output noise voltage to the input noise voltage in practice will be much smaller that unity. 11. Find the output voltage for differential amplifier, Where Vin->Induced input noise.
A. VO= -[(RF/R1)×Vd]+Vno
B. VO= -(RF/R1)×(Vd/Vno)
C. VO= -[(RF/R1)×Vd]-Vno
D. VO= -[(RF/R1)×Vd]×Vno
Answer:A
Explanation: The differential amplifier offers best immunity to induced noise because, the ratio of the output noise voltage to the input noise voltage in practice will be much smaller that unity. 11. Find the output voltage for differential amplifier, Where Vin->Induced input noise.
A. VO= -[(RF/R1)×Vd]+Vno B. VO= -(RF/R1)×(Vd/Vno) C. VO= -[(RF/R1)×Vd]-Vno D. VO= -[(RF/R1)×Vd]×Vno
Explanation: As the input of the differential amplifier is provided with induced noise voltage, the output voltage will be equal to Vo=-[(RF/R1)×Vd]+Vno
