2. Fundamental Concepts of Signal Analysis
a. What are signals? Types and characteristics
Signals are functions conveying information about phenomena, often represented as variations over time or space. They can be classified as continuous or discrete, analog or digital. Characteristics such as amplitude, frequency, and phase define the nature of these signals, influencing how they are processed and interpreted.

Recognizing repeating motifs or distinctive features within signals enables applications such as noise reduction, feature extraction, and anomaly detection. For example, identifying specific frequency patterns in heart rate signals can help diagnose arrhythmias.
3. Core Algorithms in Signal Processing
a. Fourier Transform: Basics and purpose
The Fourier Transform mathematically decomposes a time-based signal into its frequency components. It provides a spectrum showing the amplitude and phase of each frequency, crucial for understanding the signal’s structure. This transformation is fundamental in fields like acoustics, optics, and electrical engineering.
b. Fast Fourier Transform (FFT): Reducing computational complexity
The FFT is an efficient algorithm that computes the Fourier Transform in significantly fewer steps than naive methods, reducing complexity from O(N²) to O(N log N). This efficiency enables real-time processing of large data sets, vital for applications like live audio analysis or high-resolution imaging.
c. Convolution theorem: Linking time and frequency domains for efficient analysis
The convolution theorem states that convolution in the time domain corresponds to multiplication in the frequency domain. This property simplifies filtering and system analysis, allowing complex operations to be performed more efficiently by transforming signals, applying multiplications, then inverse transforming.
