Assume a transducer with a thevenin unloaded voltage of 5.0mV and a thevenin resistance of 20kilo ohms is connected to a two stage cascaded amplifier with the following specifications Rin1=50 kilo ohm Av1 (unloaded)=50 Rth1=5 kilo ohms Rth2=10 kilo ohms Av2 (unloaded)=40 Rth2=1 kilo ohms draw a amplifier model and compute the voltage across a 2 kilo ohm load?
