4 Linearizer
Figure 4-6: Output of Linearizer on Oscilloscope Screen Using Triangle Wave
Notice the mirror image effect as the voltage comes down from its maximum. If
the vertical scale and the timebase are arranged so that the slope of the
unmodified triangle wave is 45 degrees and the amplitude of the wave is 2 Volts
peak to peak, then the value of the breakpoints may be read off the screen by
measuring the distance. For example, say the distance measured is X. Then the
value of the breakpoint is X times the Volts per centimeter appropriate to the
range employed on the Y axis.
