एक FM सिग्नल का आवृत्ति विचलन (frequency deviation) fd = 15 kHz और अधिकतम मॉड्यूलेटिंग आवृत्ति fm = 5 kHz है। कार्सन के नियम (Carson's Rule) का उपयोग करके ट्रांसमिशन बैंडविड्थ की गणना कीजिए।

In amplitude modulation, if a message signal of 5 kHz is modulated by a carrier wave of frequency 900 kHz, then the frequencies of the sidebands are:

According to Nyquist's sampling theorem, a continuous band-limited signal with no frequency components higher than fm Hz can be uniquely reconstructed if it is sampled at uniform intervals spaced at most by:
