2. A waveform is depicted on an oscilloscope screen in the figure below. Given that the voltage scale (i.e. the sensitivity) was set to 2 V/Div and the time scale was 1 msec/Div, determine the amplitude and period of the waveform (remember that the axis where V 0 V may not be aligned with the x-axis on the screen, and likewise, the point where a cycle of the waveform begins may be offset from the y axis).

Solution

Amplitude = 4*2 = 8 V <------answer

4 = no of divisions of the height of the wave train

2 = Voltage/division

period, T = 4*1ms = 4 ms <------answer
