The figures below shows the connection diagram and screenshots for both the PC and phone versions. Fullwave rectifier require two AC inputs having 180 degree phase difference. Generally, this experiment is done using a center tapped transformer. In this case WG and WGbar provides the inputs. The inputs are monitored by the scope channels A1 and A2. The output is conencted to A3. A 1 kOhm load resistor is connected.
Output after connecting a 1uF filter capacitor is shown below.
