Abstract
PURPOSE:Amplifiers are series-connected by n stages which are equivalent to the dynamic range and level detection circuits are connected to the output terminals of respective amplifiers; and then the outputs are supplied to a decoders, thereby performing the automatic gain-swtiching by means of a few parts.
