SPENNINGSUTSTYRT OSCILLATOR MED MODULERINGS-KOMPENSASJON

摘要

In a compensated VCO circuit arrangement for providing constant modulation level over a wide frequency band a VCO is disclosed having a linear VCO gain factor vs. control voltage curve over the wide frequency band of interest. A compensation network is coupled to the VCO to provide an audio output having a linear output level vs. control voltage curve. By appropriately matching the two linear curves the variation in modulation level over the frequency band of interest is substantially reduced.
