Example 2
Multiplication of two
traces
Vamp ch1 = 2 vertical divisions
Vamp ch2 = 2 vertical divisions
-
math3 = ch1*ch2
As for the addition of traces, there is a even more significant high and low
overshoot.
The overshoot is due to the increased dynamics of the numbers after a
multiplication ; to avoid this and standardize the result, use the divv ()
function.
Example : If Amplitude on CH1 = 2 divv and Amplitude on CH2 = 2 divv, the
following function is used to get an amplitude of 1 divv :
math3 = (ch1 * ch2) / divv (1)
The result of the multiplication is translated into divisions on the screen.
- If Vamp ch1 = 8 div and Vamp ch2 = 8 div, the result
must be divided by divv(4) to obtain Vamp math3 = 4 div.
- When mathematical functions associated with traces are used, the
dynamics of the result obtained must be verified.
Correction of the result of the operations by mathematical functions (divv(),
divh(), / …) is recommended to optimize the screen display.
Sensitivity(ch1) = 5 V/div
Sensitivity(ch2) = 5 V/div
Vamp(ch1) = Vamp(ch2) = 10 V
