Summary
| Description |
English: A waterfall plot of a 146.52 MHZ carrier, frequency modulated by a 1,000 hz sinusoid. The modulation index has been adjusted to around 2.4, so the carrier frequency has small amplitude. Several strong sidebands are apparent; in principle an infinite number are produced in FM but the higher-order sidebands are of negligible magnitude. Plot made from a software-defined radio
Italiano: Spettro di un segnale sinusoidale a 1 kHz, con portante a 146,52 MHz, modulato in frequenza. L'indice di modulazione è pari a m = 2,4 (primo zero di Bessel), come si nota dall'assenza della portante. Sono evidenti le diverse bande laterali. |
