Four Signal Processing Themes Flashcards
Recognize broad categories of signal processing themes
1
Q
inversion = ?
A
equalization = undoing affect of system on output
2
Q
What helps recover the input signal?
A
equalization
3
Q
define filtering
A
separation of input components to reduce noise/interference
4
Q
What can be used to fix equalization problems?
A
filtering
5
Q
define identification
A
use the input and output of a system to identify mathematical models
6
Q
what do estimation and detection both do?
A
extract desired info from a signal
7
Q
what is the difference between estimation and detection?
A
estimation is when you determine the value of a parameter in a mathematical model of the system.
detection is when you determine whether a specific characteristic is present or absent
