Hi guys,
I have to make a project for school based on X10 protocol theory.
What i have to do is to build two circuits that can transmit and a receive bits over the electrical power lines.
I have found some useful materials about that but i have a problem that i cant resolve at this time.
I don't know how to build an ASK modulator (which i'm gonna use in the transmiter circuit)The modulator signal comes from a microcontroller (bits ) and the carrier is a sine wave at 100KHZ.
Can u help me please with a scheme for the ASK modulator ?? (A light one that i'll be able to undersand)
Thanks a lot
