Abstract
An improved signal conditioning compander system includes one or more weighting networks designed so that the system provides a substantially flat single-frequency sine wave sweep response through or on the transmission medium throughout the frequency bandwidth of interest. The system provides greater high-frequency weighting than heretofore practical and at the same time permits full level transmission over the entire frequency spectrum transmitted or recorded.
