Care to explain how you come to this completely incorrect conclusion?

A digital signal is one that transmits information only using two discreet states (1,0 or on,off etc.)

This is exactly how the telegraph operated, the circuit is either open or closed, and information was encoded and transmitted as a digital signal.

The fact that the Morse code used on telegraphs has variable periodicity to its signal ( .,-) does not make it non-digital because the fundamental mechanics of the device allow only on and off.

The earliest digital information transmitting, however, would be flashing a light or using reflective materials to flash sunlight in a purposeful pattern.

Semaphore is an analogue signal medium.

Because words mean things. Digital data is actual binary encoded by a computer. Clapping your hands or reflecting light isn't digital. And the variable length obviously does matter, though even if it wasn't variable length it still wouldn't be digital.

Oh, you are not understanding that "digital" is not a single usage...

In computer specific terms, sure, you are probably correct, it sounds correct.

But in the world of signal transmission, digital refers only to a data signal that can perform only two states, on and off, as opposed to analogue signals which can vary in amplitude, frequency, etc. The device encoding or decoding the signal is irrelevant, digital vs analogue is a characteristic of the signal itself.
