"Neg. Wave"
Min (Op1, 0)
Extracts the negative data points from the operand. For all positive val-
ues the result is zero. The negative values remain unmodified.
"Reciprocal"
1V / Op1
Divides 1V by the operand values.
For small operand amplitudes the result increases quickly. If the oper-
and crosses zero, the result would be a range of +∞ to -∞. In this case,
instead of 0V, the calculation function uses the value that the Least
Significant Bit (LSB) of the operand represents. (For an 8-bit value, for
example, 1/256).
You can limit the zero-crossings of the operand by using the "Maxi-
mum" operator. This limitation results in a smaller result range and a
finer resolution.
"Inverse"
Inverts all voltage values of the operand, i.e. all values are mirrored at
the ground level. Thus, a positive voltage offset becomes negative. If
the amplitude of the operand is clipped, the result is the inverted limi-
tation.
"Common
Log."
log (Op1)
Calculates the logarithm to the basis 10 of the operand. Note that the
logarithm of a negative number is undefined and the result is clipped.
"Natural Log."
ln (Op1)
Calculates the logarithm to the basis e (Euler number) of the operand.
Note that the logarithm of a negative number is undefined and the result
is clipped.
