1. A circuit or device that limits the instantaneous output signal amplitude to a predetermined maximum value, regardless of the amplitude of the input signal. 2. A chip developed by the United States Government that was to be used as the standard chip in all encrypted communications. Aside from the fact that all details of how the Clipper chip work remain classified, the biggest concern was the fact that it has an acknowledged trap door in it to allow the government to eavesdrop on anyone using Clipper provided they first obtained a wiretap warrant. This fact, along with the fact that it can't be exported from the United States, has led a number of large corporations to oppose the idea. Clipper uses an 80 bit key to perform a series of nonlinear transformation on a 64 bit data block.
