Switchable, auto gain amplifier
G. S. Phipps, J. P. Schaefer · NASA STI/Recon Technical Report N · 1988
This invention is comprised of a switchable auto gain amplifier system for amplifying electrical signals of unknown magnitude has a plurality of amplifiers having different gains, each amplifier having an input connected to a system input. A switch controllably directs only one of the amplifier outputs to a system output. The switch is controlled by comparators providing an electrical outputs indicating each saturated amplifier. 2 figs.
