@@ -4,8 +4,7 @@ This chapter describes the physical signal abstraction or "high cut" in detail.
 === Overview
 
 Physical signal abstraction allows an idealized exchange of unit-based variables between FMUs.
-In AUTOSAR, this would be equivalent to the Virtual Function Bus.
-Variables are clocked to reflect the timing aspects of the information flow.
+Variables representing these physical signals are clocked to reflect the bus timing aspects of the information flow.
 Changes to these clocked variables always reach the destination.
 
 The figure below shows an example architecture of a high-cut.
