The voltage/current at the output terminals is a function of the voltage/current at the input terminals, dependent on the mathematical function of the block.
 Note: |
|---|
If the argument of log(), ln(), or sqrt() becomes less than zero, the absolute value of the argument is used. If a divisor becomes zero or the argument of log() or ln() becomes zero, an error will result. Other problems may occur when the argument for a function in a partial derivative enters a region where that function is undefined. The argument of the trigonometric functions are in radians. |
