Question 1
If you have a photodiode in a lighting system that varies between 100 Lux and 500 Lux of light intensity, calculate the resulting photocurrent if the photodiode generates 0.02 mA per Lux.
💡 Hint: Use the given photocurrent generation rate to find the outputs at the light intensity endpoints.
Question 2
In an optical communication system, how would a change in the incident light intensity affect the output signal strength? Discuss the dynamics involved.
💡 Hint: Consider the relationship between input light and how it results in output current changes.
