The Bit-level method of speed control

uses up to seven intelligent inputs to

select from up to eight speeds. Since the

all-switches-OFF combination selects

the first speed, you only need N–1

switches to select N speeds. With Bit-

level speed control, only one input is

normally active at a time. If multiple

switches are ON, the lower numbered

input takes precedence (determines the

speed). The table and figure below

show how the input combinations work.
