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

AI Thread Summary
The discussion revolves around calculating the bandwidth of a frequency-modulated signal using Carson's Rule. A 1kHz modulating signal with a peak deviation of 5kHz on a 146.52MHz carrier is analyzed. The bandwidth calculated using Carson's Rule is proposed to be 16kHz. Participants are asked to verify if this bandwidth is accurate and reasonable when compared to the spectral plot of the FM signal. The conversation emphasizes the importance of confirming the calculation for clarity in communication.

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?
