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.
