FIELD: electrical engineering.SUBSTANCE: frequency-modulated quartz generator consists of five transistors, three resonance circuits, two resistance-capacitance circuits, two varicaps, quartz crystal resonator, paraphrase source of control voltage, two sections of long-distance lines, bias source.EFFECT: increase of frequency tuning range, decrease of incidental amplitude modulation and increase of steepness for phase-amplitude curve for frequency control of quartz generator.1 dwg |
