摘要： An electronic device for amplifying, with automatic gain control by discr values, analogue signal samples and thereafter preferably effecting analogue-to-digital conversion of the samples, consists of an amplifier circuit, a comparator circuit, and a delay store circuit. The amplifier has a basic gain during a gain control or gain ranging operation, and supplies an output sample amplified with sufficient gain to bring it into the region of a predetermined voltage. The comparator circuit compares the output of the amplifier circuit with a reference and supplies an output in accordance with the result of the comparison. For analogue-to-digital conversion the amplifier circuit supplies for an input signal U an output signal 2U - VQ, where VQ is the quantification voltage, or, in other embodiments a signal 2U.

摘要： A recirculatory analog signal sample amplifier having at least a first prtermined gain is provided with error determining means for recirculating a zero input signal with a second predetermined gain, thereby obtaining an error signal, and correction means to deduct from an incoming sample, before its circulation, a value proportional to the error signal.
