The FUN Equations
16-15
Diode (a - b) simply subtracts the value of input b from the value of input a. If the difference is
less than 0, the output value is 0.
Diode (a - b + .5) adds a constant of +.5 to the difference of (a - b), then maps all negative values
to 0. The curve is the same shape as Diode (a - b), but shifted upward 1/4 of the range between
-1 and +1.
Diode (a - b - .5) is the same curve as diode (a - b), shifted downward 1/4 of the range.
Diode (a - b + .25) shifts the curve up 1/8 of the range, and diode (a - b - .25) shifts the curve
down 1/8 of the range.
