Title: Frequency modulator
Inventor: YOSHISATO AKIYUKI
IPC: H03C3/00
Filed: 1987-11-20
Abstract: PURPOSE:To suppress spurious generation by controlling the time constant of a loop filter with an output voltage in accordance with the amplitude of the modulating signal of an amplitude detecting means. CONSTITUTION:The output of a reference oscillator 1 is M-frequency-divided by a frequency divider 2 and inputted to a phase comparator 3. A second frequency-divider 6 N-frequency-divides the output signal of a voltage control oscillator 5, feeds back it to the phase comparator 3 and phase-compares with the output signal of the frequency-divider 2. A phase difference signal is added to a loop filter 8. On the other hand, an amplitude detecting means 7 adds the output voltage in accordance with the amplitude of the modulating signal inputted from a modulating signal input terminal 11 to a variable loop filter 8 and controls a time constant in accordance with the output voltage of the means 7. A voltage controlled oscillator 5 oscillates with the frequency in accordance with the adding voltage with the output voltage of a loop filter 4 and the modulating signal voltage. When the amplitude of the modulating signal is large and the spurious is easy to occur, the time constant of the filter 4 is larger, and therefore, the generation of a spurious radiation is suppressed.
