Abstract: THERE IS DISCLOSED A CIRCUIT IN A RADIANT ENERGY ANALYZER FOR OFFSETTING AND SCALING THE RATIO OF TWO SIGNALS. THE CIRCUIT IN PART COMPRISES A FIRST CHANNEL AND A SECOND CHANNEL AMPLIFYING DEVICE. A FIRST SIGNAL IS CONNECTED TO THE FIRST CHANNEL AMPLIFYING DEVICE THE OUTPUT OF WHICH IS CONNECTED TO A FIRST VOLTAGE DIVIDER COMPONENT. A SECOND SIGNAL IS CONNECTED TO THE SECOND CHANNEL AMPLIFYING DEVICE THE OUTPUT OF WHICH IS CONNECTED TO A SECOND VOLTAGE DIVIDER COMPONENT. THE SECOND DIVIDER IS CONNECTED TO THE SECOND CHANNEL AMPLIFYING DEVICE SO AS TO PROVIDE A PORTION OF THE SECOND CHANNEL AMPLIFYING DEVICE SIGNAL OUTPUT AS DEGENERATIVE FEEDBACK. THE FIRST DIVIDER IS CONNECTED TO THE SECOND CHANNEL AMPLIFYING DEVICE SO AS TO PROVIDE A PORTION OF THE FIRST CHANNEL AMPLIFYING DEVICE OUTPUT SIGNAL IN SERIES WITH THE SECOND CHANNEL AMPLIFYING DEVICE FEEDBACK. THE RATIO OF THE SECOND SIGNAL TO THE FIRST SIGNAL AT THE OUTPUT OF THE AMPLIFYING DEVICES IS EQUAL TO A SCALE FACTOR TIMES THE DIFFERENCE BETWEEN THE INPUT SIGNAL RATIO AND AN OFFSET TERM WHERE THE OFFSET IS DETERMINED BY THE FIRST DIVIDER AND THE SCALE FACTOR BY THE SECOND DIVIDER.

Abstract: A SCALE CIRCUIT FOR USE WITH AN ANALOG VOLTAGE SIGNAL MEASURING INSTRUMENT IS DISCLOSED WHICH PROVIDES A CONTINUOUSLY VARIABLE SCALING FACTOR. THE CIRCUIT INCLUDES A LINEARLY VARIABLE IMPEDANCE RX AND A SECOND IMPEDANCE RO CONNECTED AS A POTENTIAL DIVIDER FOR RECEIVING THE SIGNAL TO BE MEASURED. A LINEAR INDICATING DEVICE IS CONNECTED TO THE VARIABLE IMPEDANCE SUCH THAT IT INDICATES THE FUNCTION

RX -+1 RO

IF THE SIGNAL DEVELOPED ACROSS THE IMPEDANCE RO IS CONNECTED TO THE MEASURING INSTRUMENT THE INDICATION ON THE INDICATING DEVICE IS THE SCALING FACTOR.
