For maximum voltage transfer between a transducer output and

For maximum voltage transfer between a transducer output and an amplifier input, use the voltage divider equation to explain the desired output impedance of the transducer and the desired input impedance of the amplifier.

Solution

Vamp=Vtrans*Ri/(Ri+Ro)

where Vamp= amplifier input voltage

Vtrans = transducer voltage

Ri= input impedance of amplifier

Ro= output impedance of transducer

for maximum Vamp Ri= infinite and Ro=0 desired you can clearly see it from above equation
