Abstract
A transceiver provides a relatively constant output voltage from its linear amplifier by providing both current and voltage feedback to its operational amplifier. The present invention utilizes common components for both transmitting and receiving and provides an apparatus which can both transmit and receive power line carrier signals which can be used to communicate digital data through phase modulation of the carrier signal. The transceiver of the present invention can be operatively connected to a microprocessor through appropriate filtering and switching.
