Question

For an optical intensity modulator, the output digital signal is Sout =11010. If we want the output signal to be 00101, which parameter of the optical intensity modulator needs to be tuned?

Answer 1

To change the output digital signal from 11010 to 00101, the optical intensity modulator needs to be tuned to adjust the intensity of the light for each bit.

Step-by-step explanation:

To change the output digital signal from 11010 to 00101, the optical intensity modulator needs to be tuned in such a way that the intensity of the light is adjusted to match the desired binary code. In this case, the optical intensity modulator needs to be adjusted to decrease the intensity of the light for the bits that need to be changed from 1 to 0, and increase the intensity for the bits that need to be changed from 0 to 1.
