Description

Arithmetic performs the following processing on the two input voltages depending on Mode

Mode	Processing	Arithmetic expression
Addition	Addition	$$V_o = Gain\cdot (V_{i2} + V_{i1})$$
Subtraction	Subtraction	$$V_o = Gain\cdot (V_{i2} - V_{i1})$$
Multiplication	Multiplication	$$V_o = Gain\cdot (V_{i2} × V_{i1})$$
Division	Division	$$V_o = Gain\cdot (V_{i2} ÷ V_{i1})$$
Min	Minimum value	$V_o = Gain\cdot V_{min}$ $V_{min}$ refers to whichever of $V_{i1}$ or $V_{i2}$ is smaller.
Max	Maximum value	$V_o = Gain\cdot V_{max}$ $V_{max}$ refers to whichever of $V_{i1}$ or $V_{i2}$ is larger.
Modulo	Remainder	Outputs the remainder of $V_o = Gain\cdot (V_{i2} ÷ V_{i1})$.
power	Power	$V_o = Gain\cdot V_{i1} ^ {V_{i2}}$

You can also set upper and lower limits on the output voltage with Minimum Voltage and Maximum Voltage.

Note

Arithmetic performs an average sample-and-hold operation.
At the end of each main period, the average value of the input voltage is sampled and the calculation is performed.
The resulting output voltage V is held during the next main period.
Therefore, this operator cannot follow a signal with a high variation frequency, and we recommend that the variation frequency of the input voltage be one tenth of the main frequency.
