A typical application for the 100MS is shown in Figure 3.
Using multiple devices within 30mm of each other can
cause them to interact by forming beat frequency interfer-
ence outputs. The 100MS can reduce this interference by as
much as a factor of 200:1 depending on the distance be-
tween the devices and their relative orientation.
