Gated Integrators and Boxcar Averagers Dual inputs Post filtering and gain adjustment The SR235 Analog Processor provides a variety of convenient signal processing functions on one or 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 The functions that can be selected are: x, x2, Vx, 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.
