## Bandwidth of Angle Modulated Signals

Estimate bandwidth, *B*_{99% }, for FM or PM signal required to transmit 99% of the power using Carson's rule.

*Fill out the fields, you can use SI suffixes in your numbers e.g. 10k would be 10 kilo. Capitalization matters, as 1m would be 1 milli and 1M would be 1 mega. Finally, press the "FM Bandwidth" or "PM Bandwidth" button to get the answer.*

FM Bandwidth_{99%}= |

PM Bandwidth_{99%}= |

Calculations are based on the following formulas:

- FM:
*B*_{99% }= 2(Δf_{max}A_{x}+f),_{x} - PM:
*B*_{99% }= 2f(β A_{x}_{x}+1).

Remember the relationship between the angular and ordinary frequency: *W*_{99% }[rad/s] = 2π[rad] · *B*_{99% }[Hz].
