Hi, I have a problem that asks me to find the minimum input impedance and maximum output impedance of an amplifier that amplifies a signal between 1k-ohm resistance source and a 5k-ohm load. The signal loss at each end from loading effects is not to exceed .5dB (total of 1dB).
I'm not really sure where to start here. How can I find the input impedance without knowing any of the voltages? I was trying to use the formula vi = (Ri/(Ri + Rs))*vs. I also do not see how the I can relate the signal loss to this.
Thanks
