Capacitors

Question 1

How are capacitors used for coupling/decoupling

Answer 1

Capacitors surpress undesirable frequencies
-Capacitors decouple one part of the circuit from another reducing the effect of noise

Question 2

How are capacitors used as high/low pass filters

Answer 2

-high-pass: Passes signals with a ƒ higher than the cut-off and attenuates signals lower than the cut-off
-Low-pass: Passes signals with ƒ lower than cut-off and attenuates signals higher than cut-off

Question 3

What are some uses of RC circuits?

Answer 3

low/high pass filters
Traffic lights
