A SIGNAL NORMALIZING AMPLIFIER
Abstract
A signal normalizing amplifier was developed for use in compressing the level of signals having a wide ynamic range to a l vel sui able for recording on mag tic tap or other media having limited dynamic range. Signal compression is effected by automatic ac ion of the amplifier, which c anges i s gain in discrete 10-db steps. Signal distortion is limited to a very small transient of short duration, which occurs only during the transitional period. The gain of this amplifier varies from zero to 40 db although other r nges may be easily incorporated. I ad ition to t signal output, the amplifier provide an indication of amplifier gain which may be used in reconstructing or otherwise recovering information concerning the full dynamic range of the original signal. The completely solid-state design, its operation, the circuitry involved, the a just ent proc dure, and the specifications of the laboratory model are de cribed. (Author)
