Experiments in time shift keying in data communications.

A communication system based on Time Shift Keying (TSK) that allows for file transfer between two computers through a coaxial cable. The system consists of a source computer interfaced to a transmitter and a receiving computer interface to a receiver. The system operates in simplex mode. The transmit side of the system uses a microcontroller to control the frequency that represents logic \u27I\u27 and logic \u27O\u27. The receive side also uses a microcontroller to determine the time differences in the carrier signal and translates these differences into either logic \u27I\u27 or logic \u27O\u27. A Graphical User Interface (GUI) based software controls the opening and closing of the source and receive computer. The software allows the user to send or receive files
