SR235 Analog math processor w/ 36 functions
(Click to enlarge)
SR235 Analog Math Processor
  • 36 functions
  • Dual inputs
  • Post filtering and gain adjustment
  • 2 % basic accuracy
The SR235 Analog Processor provides a variety of convenient signal processing functions on up to two inputs. Background subtraction, ratioing and logarithmic compression are just a few of the functions which can be implemented with the SR235. With its many output functions, high accuracy, and variable filtering and gain, the SR235 is the perfect addition for any boxcar system—especially those in which a computer is unavailable to perform signal processing.

SR235 Analog Math Processor

The SR235 Analog Processor provides a variety of convenient signal processing functions on up to two inputs. Background subtraction, ratioing and logarithmic compression are just a few of the functions which can be implemented with the SR235. With its many output functions, high accuracy, and variable filtering and gain, the SR235 is the perfect addition for any boxcar system—especially those in which a computer is unavailable to perform signal processing.

The SR235 outputs a voltage proportional to a function of an argument formed from its two inputs, A and B. Allowable arguments are: A, B, √(A2 + B2), A-B, A×B/10, and 10A/|B|. The functions that can be selected are: x, x2, √x, ln|x|, -dx/dt, and -(dx/dt)/100. Filtering can be performed on the argument with time constants from 0.3 ms to 30 s.
