rimodulati

Rimodulati is the plural form of rimodulato, an Italian term used in telecommunications to describe signals, carriers, or data streams that have undergone remodulation—the application of a second modulation to an already modulated signal. Rimodulazione is the process itself. The concept arises in systems where a signal must be shifted, re-encoded, or repartitioned within a transmission chain.

In practice, rimodulazione may be employed to shift carrier frequency, adapt to a different channel bandwidth, multiplex additional data, or implement alternative modulation formats within a single transmission path. It can be used to repurpose existing signals for new services or to integrate multiple data streams into a common channel without fully demodulating the original content.

Common contexts include remodulation at intermediate frequencies in radio receivers, satellite and cable systems, and digital broadcasting where channel reallocation or format changes are required. Rimodulati are the output of such processes and may require synchronization and error protection to preserve data integrity.

Considerations: remodulation can introduce additional noise, distortion, and latency; compatibility of modulation schemes, timing, and error-correction protocols is essential. The term is primarily found in Italian technical literature, while English-language sources typically use remodulation or re-modulation to describe similar concepts.
