Power line communication system and method

摘要: The power line communication system includes a transmitter and receiver, both providing path between two control devices over line. voltage amplifier current amplifier. A switch the transmit receive modes is implemented within also has two-step output impedance. When active, shows low impedance on to overcome other loads. If, however, medium high level of noise, decreases even further creates ground. receiver advantageously uses logarithmic for signal range compression. This type preserves shape that important when modulation scheme zero crossings store information. At communications device mixes reference with signals received mixed then amplified before passing output. device, demodulated so as detect whether what noise or signal.
