Chapter 0094 Thesis

The concept of wired telegraphy is actually quite simple.

It involves converting information into electric current, which is transmitted via a wire and received at the terminal.

So, a telegraph transmitter is essentially a key-controlled signal transmitter, and the receiver is a decoder.

The principle of a manual telegraph machine involves a person operating an electrical key. The signals are formed by 'dots' and 'dashes' and transmitted via a wire.

Morse also built on his predecessors' work by designing a set of codes for letters and numbers that made transmission via circuits easier.

You don't need a complex circuit, just one line can solve the problem!

Simply put, it's like a piece of paper that either has or hasn't been punched through.

But it's this kind of improvement, which is much more reliable than the electrolytic signal, and it is the foundation of the development of wired telegraphy.

What Su Lu intends to present is this method of encoding and decoding.
