on an oscilloscope grid, the vertical axis is set to 1V/division, and the horizontal (time) axis is set to 1 ms/division.The postion of the CRT trace has been adjusted so that zero volt(ground) corresponds to the horizontal line in the center ofthe grid. if a signal v(t) = 2 V sin [2p (250Hz) t] is applied tothe scop input, sketch the waveform you would expect to see. (Assume t=0 corresponds to the left-most vertical line)
