However, this connection has the disadvantage of loading the source down with the

series combination (sum) of the two resistors. For ra and rb, for example, if the input

impedance rs is 1k Ohm, and each of the two resistors is 100k Ohm, then the resis-

tors load down the signal source with 200 Ohm (100 Ohm+ 100 Ohm), resulting in a

0.5% gain error. The following gives a simplified representation of the circuit and cal-

culating process.
