How does the telephone's analog transmission differ from the signaling of the harmonic telegraph?
Answer
It uses a continuous electrical wave that mirrors the original sound wave
The harmonic telegraph relied on discrete, multiplexed musical tones, which functioned essentially as a form of digital or intermittent signaling. In contrast, the telephone operates on the principle of analog transmission, where the electrical current varies continuously in a pattern that matches the pressure waves of human speech. This continuous modulation is what allows for the faithful reproduction of complex sounds, such as the human voice, rather than just simple, separate tones.
