Repeaters: Signal Regeneration Hubs wɔ Nkitahodi Ntrɛwmu mu

Repeaters yɛ nneɛma a ɛho hia wɔ nnɛyi nkitahodi nhyehyɛe ahorow mu. Wɔn adwuma titiriw ne sɛ wobedi sɛnkyerɛnne a ɛsɛe a efi akyirikyiri a ɛyɛ mmerɛw anaasɛ ntwitwiridii bere a wɔde mena no ho dwuma. Sɛ́ ade titiriw a ɛwɔ honam fam ade no mu no, wɔn a wɔsan yɛ no de ɛlɛtrɔnik nsɛnkyerɛnne ho nhyehyɛe a ɛyɛ pɛpɛɛpɛ di dwuma de trɛw nkitahodi nkitahodi ahorow mu ma wotumi de ho to so.

Wɔ mfiridwuma mu no, repeaters yɛ adwuma wɔ full-duplex mode mu, ɛma amplifying, shaping, na retiming mfitiase signal a attenuated wɔ receiving awiei no. Sɛ anyinam ahoɔden anaa aniwa so nsɛnkyerɛnne tu kwan tenten a, wɔn amplitude no sɛe nkakrankakra na wɔn asorɔkye ahorow no kyinkyim. Saa distortion yi betumi ama bit error rates akɔ soro wɔ receiving end. Repeaters san de sɛnkyerɛnne ahoɔden ba denam high-precision amplification circuits a wɔde di dwuma so na wɔde waveform shaping technology di dwuma de yi dede a ɛtwetwe adwene fi hɔ, awiei koraa no wɔsan de sɛnkyerɛnne a wɔayɛ ho adwuma na ɛho tew no kɔ transmission medium a edi hɔ no so. Wɔ fiber-optic nkitahodi mu no, optoelectronic repeaters nso tumi yɛ optical-to-electrical-to-optical nsakrae, wɔ ɔkwan a etu mpɔn so trɛw fiber nkrasɛm akwansin mu kɔ kilomita ɔhaha pii.

Repeaters wɔ nneɛma ahorow pii a wɔde di dwuma. Wɔ atetesɛm wired ntwamutam mu no, twisted-pair Ethernet de hubs (titiriw no repeaters) di dwuma de ka node ahorow pii bom; wireless communication base stations de wɔn ho to relay stations so de trɛw coverage mu; na ahunmu a emu dɔ hwehwɛ asɛmpatrɛw adwuma ahorow de wɔn ho to relay satellite ahorow a ɛtoatoa so so de yɛ nkitahodi kwan a ɛda Asase ne Ɔsram ntam. Wɔ nnɛyi Industrial Internet of Things mu no, interference-resistant repeaters hwɛ hu sɛ data a wɔde mena a ɛyɛ den wɔ mmeae a emu yɛ den.
