Welcome, analyst.
A covert communication has been intercepted, but it’s not written in plain text. Instead, the message has been encoded and hidden inside what appears to be electrical signal data. Your task is to uncover the original secret.
The captured data consists of paired signals labeled Signal A and Signal B, each carrying voltage values. At first glance, the values seem simple, just 2V and 7V, but their meaning lies not in the individual values, but in their relationship to each other.
Somewhere within this structured data lies a hidden binary message. Every pair of signals encodes a single bit, and every sequence of bits forms characters. The full sequence reconstructs a secret message, but only if you interpret the signals correctly.
Can you figure out which levels correspond to binary '1' and '0'?
