Where:
V
end
= The source value at the end point
V
start
= The source value at the start point
N
= The number of points in the sweep
A
= The asymptote value
The number of points in a sweep is one greater than the number of steps in the sweep.
The following figure is an example of a five-point logarithmic sweep from 1 V to 10 V.
