Means for linearizing a voltage variable capacitor controlled oscillator |
摘要 |
Frequency modulation of an information signal is provided by applying the signal to series connected voltage variable capacity diodes. The reactance of the diodes is coupled through a transmission line to a cavity oscillator. The varying diode reactance causes a corresponding change in the frequency of modulation of the oscillator. The improvement comprises a linearization potentiometer which couples to the diodes and provides a means to vary the effective impedance presented to the cavity oscillator such that a linear change in signal voltage applied to the diodes results in a linear change of oscillator frequency.
