What will I learn?
The Mathematics of Series Course provides practical tools to analyse discrete-time signals, covering basic sequence behaviour, convergence tests, energy, power, and square-summability. Explore Fourier-type concepts, DTFT, finite trigonometric approximations, with focus on least squares, numerical conditioning, and rigorous proofs for high-quality results in real-world applications.
Elevify advantages
Develop skills
- Master discrete-time series: build, analyse, and classify key signal sequences.
