Signal Conditioning Flashcards
1
Q
What does an IR sensor do?
A
It measures changes in the ground colour. The output of the IR sensor will change proportionally to the IR signal reflected by the track.
2
Q
How do we control the forward current of an IR sensor?
A
Iforward = Vdc - Vf / Rb
Where Rb is a bias resistor
3
Q
Can the output voltage of an op amp ever reach its rail voltages?
A
No, it is only able to get within a few volts.
4
Q
What is isolation?
A
It is used to prevent the transfer of AC and DC signals between different parts of the system while still allowing data transfer.
