PRESET-FREQUENCY CONTROLLED OSCILLATOR Russian patent published in 1998 - IPC

FIELD: radio electronics; miscellaneous devices including controlled local oscillators or digital sensors of set of frequencies. SUBSTANCE: oscillator has self-excited mode oscillator G, pulse shaper, variable-ratio frequency divider that functions to calculate absolute error relative to rated value and to determine its polarity, m-input Gray code to positional binary code converter, 2x2AND-OR-NOT gate, positional binary code adder, positional binary code register, functional converter, positional binary code buffer register, positional binary code to Gray code converter, subtraction circuit, trigger pulse rise time detector, four delay circuits, fixed-ratio frequency divider, inverter, first RS flip-flop, second RS flip-flop, and 2OR-NOT inverse-logic gate. EFFECT: improved speed due to use of variable-ratio divider. 4 dwg, 1 tbl
