Digital Signal Processing
- Focuses on representation, analysis, and processing of signals, especially digital signals.
- Signals are functions of one or more independent variables.
- Discrete-time signals can be represented as 𝑥 𝑛 = 𝑥𝑎 𝑛𝑇𝑠, where 𝑛: integer.
- Continuous-time signals are functions of one or more independent variables.
Sampling Theorem
- Nyquist-Shannon sampling theorem dictates sampling frequency must be at least twice the maximum frequency present in the signal for perfect reconstruction.
