Angle Modulation Presentation Transcript:
1.Angle Modulation
2.This scheme is called Frequency Shift Keying (FSK) where information digits are transmitted by keying different frequencies.
3.Bandwidth of Angle Modulated Waves
4.Generation of NBFM
5.WBFM
A better bandwidth estimate is:
For a truly wideband case,
The “deviation ratio” plays a role similar to the “modulation index” in AM.
