Power line carrier system is common in home appliances networking. One benefit of using this kind of transmission line is that we don’t have to deal with additional wiring for data or signal communication, since all we need is already provided when we plug the power jack into the power outlet/stop contact. The circuit depicted in the schematic diagram below […]

This is Powerline Audio Transmission circuit using LM1893. This circuit uses LM1893 that is designed to allow analog data reception and transmission. The carrier is modulated by base-band audio-bandwidth signals FM passing through the tuned transformer onto the power line. The receiver PLL will demodulates the modulated carrier linearly. Here is the schematic diagram of the circuit: External audio amplification […]

This schematic diagram shows an LM1893 powerline modem circuit. This circuit is used to transfer information between remote location by using the power mains. This circuit uses LM1893 that is used as a power line interface for half-duplex (bi-directional) communication of serial bit stream of virtually any coding. Here is the schematic diagram of the circuit : To give maximum […]
