Web22 de oct. de 2024 · Narrowband refers to radio communications whose signal bandwidth is within the coherence band of a frequency channel. This means the bandwidth of the signal does not significantly exceed the coherent bandwidth of the frequency channel. Narrowband systems divide the total frequency spectrum into several narrowband … WebAnswer – (4) 30. An FM signal with modulation index of 9 is applied to a frequency triple. Then. modulation index will become 1. modulation index will become 30. modulation index will become 9. modulation index will become 27.
