A voltage divider is used to reduce the amplitude of a signal from a generator that is fed into an amplifier. The output impedance of the generator is 6002, and its open-circuit output voltage is 8 volts peak-to-peak. The amplifier's input impedance is 100 kn. The equivalent circuit is shown below. ww- 600 a 100k Amp Generator (a) Select resistors R1 and R2 to reduce the amplitude by a factor of 4, using the "factor of 10" approximation discussed in Hayes, section 1N.4.6. (b) Find the Thvenin equivalent of the combination of generator + divider (the circuit inside the dotted line). You must determine RTh and VTh- (c) Use your resulting Thvenin equivalent to determine exactly what voltage the amplifier now sees.
