Abstract
Abstract A digital scaler adjusts the processing of an input signal to a digital fback integrator by a multiplying technique which is implemented by shifting the connections between an analog-to-digital converter and the input to an adder, both forming the input section of a digital feedback integrator, in order to maintain a constant dynamic range of the output signal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
51 words
In a digital integrator device having input signal conditioning means and signal integrating means, the improvement comprising: signal multiplying means for adjusting the magnitude of an input signal in accordance with the number of signals to be integrated, said multiplying means being connected between said conditioning means and said integrating means.
Claim 2
Dependent Claim
51 words
In a digital integrator device having input signal conditioning means and signal integrating means, the improvement comprising: signal multiplying means for adjusting the magnitude of an input signal in accordance with the number of signals to be integrated, said multiplying means being connected between said conditioning means and said integrating means.
Claim 3
Dependent Claim
49 words
