Oscilloscope time base problem. you are asked to display a 1 khzsine wave signal on the screen. since the period t is related tothe frequency f by the formula t = 1 / f, the period of this waveis 1/(103/s)=1ms, so a reasonable setting for the"time/div" dial is 1 ms/div. but suppose you select aninappropriate setting for the time/div dial by mistake. what wouldyou see if you set the dial on 1 μ s/div? 100 ms/div? a. asine wave shifted to the left on 1 μ s/div and to the right on100 ms/divb. a(nearly) horizontal line on 1 μ s/div andmany (nearly) vertical lines of 100 ms/divc. nothing on either (no trigger)d. anormal sine wave in both casese. none of these
