| 11. | Popular analog modulation techniques include amplitude modulation and frequency modulation.
|
| 12. | His main research interests during this period were in frequency modulation and parametric oscillations.
|
| 13. | Channels 1-3 must use " narrowband " frequency modulation ( 2.5 kHz deviation ).
|
| 14. | In frequency modulation, amplitude variation at the microphone causes the transmitter frequency to fluctuate.
|
| 15. | One of the station's listeners was the inventor of frequency modulation, Edwin Howard Armstrong.
|
| 16. | Possibly his best known discovery was the wide-band frequency modulation.
|
| 17. | Frequency modulation is most commonly generated at the operating frequency with the required deviation.
|
| 18. | The answer to both needs was wideband FM-frequency modulation.
|
| 19. | FM broadcast signals also feature wide frequency modulation, hence EME reception is generally not possible.
|
| 20. | The IBM PC cassette interface encodes data using frequency modulation with a variable data rate.
