In signal processing , what do the term 'feature' means?

AI Thread Summary
In signal processing, the term 'feature' refers to specific characteristics extracted from data to aid in analysis or task completion. Feature extraction is crucial for applications like speech recognition, where cepstral coefficients are commonly used. It also plays a role in techniques such as linear predictive coding and audio compression methods like MP3. Understanding these features allows for improved processing and interpretation of audio signals. Overall, features are essential for enhancing the effectiveness of signal processing tasks.

Feature extraction can mean whatever characteristic you may be interested in knowing about to accomplish your task.

For example extraction of cepstral coefficients for speech recognition.

You can read about the feature extraction required to perform linear predictive coding.

Or read about mp3 compression.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
