Unformatted text preview: at the output terminal is only half the voltage provided by the generator: . 2 1 50 50 50 G G out V V V = + = The generator compensates for this by doubling the amplitude of the signal it provides. Most circuits used in ECE 210 lab, however, have input resistances much greater than 50 & (Figure 3). The voltage at the output terminal is the same as the voltage provided by the generator: . 50 G L L G L L G out V R R V R R V V = + = Therefore, default setting of the generator produces double the specified output. Instead, the output termination needs to be changed to High Z.
