What process converted a biological signal into a radio frequency signal for transmission during early space monitoring?
Answer
Telemetry
The underpinning technology that allowed for the transmission of astronaut vital signs from orbit was telemetry. This process was essential for converting a biological signal—such as the electrical impulse recorded by a heart monitor—into a radio frequency signal capable of traveling reliably through the air over great distances. Once received miles away, this signal could then be reassembled back into readable, actionable diagnostic data. The necessity of this conversion spurred crucial engineering groundwork related to miniaturization and maintaining signal reliability under severe environmental stress, proving vital for later medical applications.
