Well the way I would do it is to draw a line from the 2 on the left hand
side until it crosses the diagonal line and then draw a line down to the
frequency number at the bottom. I have done this using a dotted line. Then
we have to judge what frequencies it would be as there is no number.
Well it is about 150Mhz. and that is near enough for the conversion.
Calculations are not required for the exercise just
an interpretation of the chart. |
