analog computer engineering. SUBSTANCE: device designed for specific computations, analog-to- digital converters computing exponential function of Y = Xm at device output relative to input signal X and exponent m, as well as for computing logarithm or antilogarithm of input signal has two logarithmic converters; output of first logarithmic converter functions as input of exponent setting unit and output of second logarithmic converter serves as inverting input of operational amplifier whose noninverting input functions as output of exponent setting unit; operational amplifier output functions as data input of second logarithmic converter and as output of device; logarithmic converter has first and second inverting adders and multiplier. EFFECT: improved of logarithmic conversion. 2 cl, 3 dwg |
