What is the bandwidth of a modulated signal?

The modulation bandwidth of the RSOA is typically in the range of 1–3 GHz. This bandwidth is in principle determined by the carrier lifetime [204]. However, it usually becomes smaller than this maximum value due to the electrical parasitics associated with the packaging.

How do you calculate bandwidth of a modulated signal?

You can predict the bandwidth in this case using the simple formula: BW = 2fm where fm is the frequency of the simple sine wave used to modulate with.

What is BW of amplitude modulated signal?

Thus AM wave has bandwidth of 2ωc+ωm−2ωc−ωm =22ωm. i.e. twice the signal frequency is produced.

What is BW of FM?

Wideband FM is used for FM broadcasting, in which music and speech are transmitted with up to 75 kHz deviation from the center frequency and carry audio with up to a 20 kHz bandwidth and subcarriers up to 92 kHz.
