• Signals and systems can be classified based on various criteria such as continuous-time or discrete-time, analog or digital, deterministic or random.
• The frequency domain representation of signals involves using Fourier concepts to understand how different frequencies contribute to the signal’s overall behavior.
• Systems can be classified based on their properties, such as linearity, time-invariance, causality, and stability. The response of Linear Time-Invariant (LTI) systems can be determined using techniques like convolution.
• Sampling involves capturing discrete points from a continuous signal. There are various sampling techniques such as uniform sampling, non-uniform sampling, and oversampling.
• Laplace and z-transforms are mathematical tools used to analyze signals and systems in continuous and discrete domains, respectively. They help in simplifying complex problems and understanding system behavior in terms of poles, zeros, and transfer functions.
