1. An instantaneous floating point amplifier, comprisingan analog signal input summation network for receiving analog data signals,synchronized means for storing a predetermined value of offset voltage said synchronized means coupled to said analog signal input summation network for effectively subtracting an offset voltage component from said analog data signals,a sample-and-hold network coupled to receive an output signal from said summation network,cascaded amplifier means coupled to said sample-and-hold network for developing an analog mantissa value for said sampled-and-held data and a digital gain word related thereto, andan analog-to-digital converter coupled to said cascaded amplifier means for converting said analog mantissa value to a digital mantissa value, which, with said digital gain word, represents in digital form said sample analog data.
