The time/div and voltage/div axes of an oscilloscope have been erased. When a 1 kHz, 5V p-p square wave calibration pulse is connected to channel 1 ofthe scope the waveform observed on the screen is as shown in the upper trace of the figure. An unknown signal is connected to channel 2 (lower trace) ofthe scope. If the time/div and V/div on both channels are the same, the amplitude (pp) and period of the unknown signal are respectively.
