<p>An angle modulator operated intermittently for the reduction of the power consumption of radio equipment, and so on, receives a frequency control voltage and an input modulating signal at different terminals of a variable capacitance diode (D) so that the frequency control voltage is applied directly to the variable capacitance diode without being affected by the coupling capacitor for the modulating signal. This allows a quick response to the frequency control signal and a rapid tuning after the start-up of the modulator.</p> |
