3. Implementation
The Table block is used to perform a non-linear look up operation y = f(X_IN), and
output a value using the following formula: OUT = f(X_IN) × GAIN × INP.
Where:
Y is calculated as a function of X IN by using the selected TABLE values.
A TABLE is defined as an array (2 × 16) in size, of x,y points where x values are
entered in ascending order. (Refer to section 6.3.4, Tables Menu, for additional
explanation.)
If X_IN is less than the first X value in the TABLE, then f(X_IN) = the first y
0
value.
If X_IN is greater than the last X value in the TABLE, then f(X_IN) = the y
15
point.
If X_IN equals an X value in the TABLE, then f(X_IN) = the y value associated
with that X point.
If X_IN falls between two X values in the TABLE, then f(X_IN) is the
interpolated between the two associated y values.
