Intro METHODS First, the function generator is set to be a square wave with a 2.5 volt amplitude or 5 volt peak to peak. The frequency is set to 20 Hz with duty cycle of 50% and the offset is adjusted so that the signal ranges from zero to five volts. Next, the RC circuit is then constructed according to the given diagram and one ociliscope chennel is connected across the function generator and another is connected across the capacator. Both voltages are then displayed on the ociliscope and are shown ?WHERE?.
