FIELD: automation and analog computer engineering, in particular, design of analog computers, regulation and control devices. SUBSTANCE: device has first and second relational processors, each of which has two-position switch and comparator. First relational processor is designed as hysteresis relational processor, which comparator output is connected to its direct input through feedback circuit resistor. EFFECT: increased functional capabilities of device due to increased number of types of hysteresis functions, simplified design due to decreased number of switches. 7 dwg
