What technological advancement allowed digital beacons to analyze signals more effectively than analog versions?

Answer

Microprocessors

The transition from analog to digital technology in the 1970s and 1980s was defined by the integration of microprocessors. Unlike analog receivers that forced users to interpret fluctuating audio tones to judge signal strength, digital processors could analyze incoming signal data far more intelligently. This shift made the search process faster, more intuitive, and less prone to user error, fundamentally redefining how victims are located.
