ABSTRACT:
In accordance with the teachings of this invention, a multi-path distortion simulator is constructed having two paths, one path including a delay means, and both paths including phase shifters and attenuators. The phase shifters are closely matched, thereby compensating for drift and errors in the phase shifters. Similarly, the attenuators are closely matched, thereby compensating for drift and errors in the attenuators.
