Abstract :
The telegraph training device connect to PC with USB interface helps the telegraph operators to exercise. The core of hardware is STC89C52; After being shaped by pretreatment circuit, the key signal is identified to morse code by adaptive algorithm, and then sent back to the computer. Additional noise superimposed with keying sound is to adjust the training difficulty.
