Perhaps you should try some spelling variations:
multirate processing » multi processing (Expand search), multiuser processing (Expand search), multimedia processing (Expand search)
decrease multirate » decrease intimate (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that increase » an increase (Expand search), not increase (Expand search), can increase (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease to decrease multirate processing ) OR ( decrease that increase OR decrease ))~.
