FUJITSU's Digital Modulation

FUJITSU'S Digital Modulation using Current output D/A Converter (IDAC) can change ideal frequency modulation. > This way leads high EMI reduction efficiency. Cycle-Cycle jitter is smaller.

Uniformed-Peak Spectrum can be realized by the peak dispersion depending on Variable modulation frequency.

 FUJITSU's Digital Modulation

 Conventional Analog Modulation

Conventional Analog Modulation Circuit generates a modulated waveform with distortion or slow-down depending on analog control modulation.(show the above fig.) > We can see about 3dB Peak on spectrum waveform.

Because Conventional Analog Modulation Circuit uses single modulation frequency ,we can see the peak at modulation frequency intervals.

Compound Modulation Frequency

 New: compound modulation freq.

 Conventional: single modulation freq.
