FIELD: electric signal generation. SUBSTANCE: functional generator synchronously produces relay, linear, and sine functions and has series-connected delta voltage generator and inertialess functional converter reproducing piecewise linear sine function. Main part of functional generator is complex inverter built around operational amplifier with opposing symmetrical circuits at input and in feedback circuit in the form of multisection resistive voltage dividers whose taps are connected to transistor bases. Emitter circuits of transistors are connected through resistive matrix to main input of functional generator to form sine function and collector circuits are integrated to form differences in linear and sine functions. EFFECT: enhanced precision and enlarged functional capabilities. 1 cl, 1 dwg |
