(a) Frequency responses of the WLED with (red curve) and without (brown curve) the equalizer. (b) Combined frequency responses of the two modulated channels (green and blue) of the RGBW LED with (green curve) and without (black curve) the passive equalizer. In both figures, we explicitly indicate the 3 dB BWs for the various cases.
