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. How big is Signal processing?Machine learning for signal processing, computational imaging, and AI-driven signal analysis
2. What is the core mathematical foundation?Fourier analysis, linear systems theory, probability, and statistics
3. What is the key transformation?Analog-to-digital conversion (sampling and quantization)
4. How does signal processing help make music sound better?It removes unwanted noise, sharpens the sounds we want, and can even change the music so it fits better on speakers or headphones.
5. Why do we need to turn analog signals into digital ones?Digital signals let computers do precise math on them, so we can edit, store, and send them more easily and accurately.

Sampling Rate: The number of samples taken per second from a continuous analog signal.
Quantization: The process of mapping a continuous range of values to a finite set of discrete values.
Modulation: The process of varying one or more properties of a periodic waveform to transmit information.
