ABSTRACT:
A processor responsive to multiple AC analog signals has individual sampling circuits to sample and hold each AC analog signal in DC form. After the DC signals are multiplexed, a single error correction circuit calculates correction voltages individualized for each sampling circuit and sums them with the DC signals. An instantaneous floating point amplifier amplifies each signal in 12 db increments up to a preselected limit, and then a second sampling circuit holds the amplified signal before an analog-to-digital converter generates a digital signal representative of the amplified signal.
