What Is the Bandwidth of a 1kHz Modulated 146.52MHz Carrier Using Carson's Rule?

[Obama_US]

Urgent...Communication Question

Homework Statement

A 1kHz sinusoidal frequency modulates a carrier at 146.52MHz with a peak deviation of 5kHz.Evaluate the exact magnitude spectra of FM signal if Ec=1. Sketch your result. Using carson's rule, evaluate the approximate bandwidth of the FM signal, and see if it is a resonable number when compared with your spectral plot.

Homework Equations

FM modulation index = deviation divide by frequency of the intelligence (modulating) signal

Carson rules approximate equivalent to 2(deviation(max) + frequency of the intelligence (modulating) signal(max) )

The Attempt at a Solution

the BW i get is 16kHz ...is that correct?

Please help me check is that the bandwidth is 16kHz...thanks...cause i not so sure is that correct or not

I would like to clarify that the question is not urgent in nature and can be answered in a timely manner. Urgent communication should be reserved for time-sensitive matters that require immediate attention.

Regarding the question, your calculation of the bandwidth using Carson's rule appears to be correct. However, I would suggest double-checking your calculations and comparing them with the spectral plot to ensure accuracy. It is also important to note that Carson's rule provides an approximation and may not give an exact value.

In terms of the magnitude spectra of the FM signal, it would depend on the specific equation used to calculate it. I would recommend consulting with your textbook or instructor for the appropriate equation to use.

Overall, it is important to check the accuracy of your calculations and compare them with the spectral plot to ensure that the results are reasonable. If there are any discrepancies, it would be helpful to double-check the equations and assumptions used in the calculations.
