Abstract
Apparatus and system for communicating data via a power line. The apparatus comprises a transmitter comprising a modulator for generating a second digital signal based on input data; a digital buffer for amplifying the second digital signal to generate a third digital signal; a filter for filtering the third digital signal to generate an analog output waveform; and a coupler for coupling the analog output waveform to the power line.
Claims8
Apparatus for communicating via a power line, comprising:
- a transmitter comprising a modulator for generating a second digital signal based on input data;
- a digital buffer for amplifying the second digital signal to generate a third digital signal;
- a filter for filtering the third digital signal to generate an analog output waveform that complies with at least one standard for Power Line Communication (PLC);
- and
- a coupler for coupling the analog output waveform to the power line;
- wherein the modulator further comprises a direct digital synthesizer for generating a first digital signal based on the input data and a delta-sigma modulator for generating the second digital signal based on the first digital signal.
