Intro to Electrical Engineering Flashcards
1
Q
What does a Low pass filter do?
A
It only allows low-frequency signals from 0Hz to Its cut-off frequency
2
Q
What does a High pass filter do?
A
It only allows high frequency signals from its cut-off
frequency and higher to infinity to pass through while blocking those any lower
3
Q
What is critical frequency?
A
the point where both impedances are equal
4
Q
What is Vpp?
A
The peak to peak voltage on a wave
5
Q
What can a diode do?
A
Diodes are semiconducters that can convert AC to DC
6
Q
What is rectification?
A
changing of AC to DC
7
Q
What happens to a diode when conducting electricity?
A
It doesn’t obey V = I R
8
Q
What does a capcitor do to a wave on a graph?
A
It smoothens the wave making it a straight line
9
Q
What does a zener diode do?
A
It prevents the voltage going above a certain level
