👉 In the context of telecommunications, a telectrograph is a device used for measuring electrical signals. It consists of a long, thin wire that is connected to a microphone or speaker and can be adjusted to pick up different frequencies of sound. The telectrograph measures the voltage difference between the two ends of the wire and converts it into a readable signal on a monitor or display. This process is crucial for analyzing electrical signals in telecommunications systems, enabling engineers to troubleshoot problems and optimize system performance
