Analog Circuits Modeling

This lecture introduces a series of chapters on the design of analog circuits, focusing on equivalent circuits to model mechanical and acoustic systems. The instructor discusses electrical circuits, conventions for generators and receivers, transformers, biports, and quadripoles. The lecture covers symmetrical and antisymmetrical conventions, the concept of impedance, and the analogy between mechanical and electrical systems. The instructor explains how to represent mechanical systems using electrical circuit analogies, such as mass-spring-damper systems. The lecture also delves into the concept of impedance in mechanical systems, the resonance frequency, and the relationship between force, velocity, and displacement. Practical examples are provided to illustrate the application of circuit modeling in analyzing mechanical systems.
