Fig. 6 — This experiment is based on PWM and FH-4DPSK modulation for PLC and VLC. a The communication waveforms of the sent data (CH1), the data received via visible light (CH2) and the data received via the power line (CH3). b The waveforms of sent data (CH1), conditioned signal in light receiver (CH2), output voltage (CH3) and input voltage (CH4). Zoomed views of the waveforms are the conditioned signal and the input/output voltages in the common operation and communication states.
