Defining Signals Signals are functions that convey information about the behavior or attributes of some phenomenon. They can be classified in various ways: - Analog vs. Digital Signals - Analog Signals: Continuous in time and amplitude (e.g., speech, music). - Digital Signals: Discrete in time and amplitude, represented in binary form. - Periodic vs. Aperiodic Signals - Periodic: Repeat after a fixed interval. - Aperiodic: Do not exhibit periodicity. - Deterministic vs. Random Signals - Deterministic: Completely predictable. - Random: Contain inherent randomness, often modeled statistically. Understanding Systems Systems are entities that process input signals to produce output signals. They can be characterized as: - Linear vs. Nonlinear - Time-Invariant vs. Time- Variant - Causal vs. Non-causal - Stable vs. Unstable The analysis of signals and systems involves understanding their properties, behaviors, and how they interact.
