Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the signal processing domain?Operates in either the time or frequency domain to modify signal characteristics
2. What is the implementation methods?Can be realized using analog electronic circuits or digital algorithms (DSP)
3. What is a weighting filter and why do scientists use it?A weighting filter changes parts of a signal so that important parts stand out. It helps scientists see hidden patterns in noisy data.
4. How does a weighting filter make some sounds louder or quieter?It gives different “weights” to different frequencies, so some sounds get a boost while others are cut down.

Signal-to-Noise Ratio (SNR): A measure that compares the level of a desired signal to the level of background noise.
Frequency Response: A measure of how a system's output amplitude and phase vary with the frequency of the input signal.
Impulse Response: The output of a system when presented with a brief input signal (an impulse), which characterizes the system's behavior.
