Title

Schematic Diagram of a Correction System

Description

We consider a communication system and an observer (or auxiliary device) who can see both what is sent and what is recovered (with errors due to noise). This observer notes the errors in the recovered message and transmits data to the receiving point over a “correction channel” to enable the receiver to correct the errors. The situation is indicated schematically in [the Figure].
