hi everyone , i am doing a project on power line carrier communication,
i am managed to get a modulated FSK signal which i am going to ride over a 50Hz/220VAC line. i am using a 89C51 microcontroller and XR2206 as a modulator. i need help in a line coupler/driver.
Also in the contruction of the transformer coupling my transmitter to the mains. i am using 120Khz carrier as a logic 1 and an abscence of 120khz alogic '0'.which will appear as a burst near the zero level of the 50Hz mains frequency.
And plz tell me what i could use in place of a transil (in the above requirements) in the line coupler .
i thank u all for u time and consideration.
