NOTES: The following notes cover the measurement methods in case the measuring crosstalk of G → R:
7. Apply the data to G only and measure the power of the frequency component of the data at ROUT.
8. Apply the data to R only and measure the power of the frequency component of the data at ROUT.
9. Take the difference of the above two powers. The unit is in dB.
