Compensation Circuits: Response Time and Bandwidth

This lecture covers passive electric compensation circuits for first-order systems, focusing on decreasing response time and increasing bandwidth. It explains compensator transfer functions, combined sensor and compensator responses, and the impact of compensation on sensor output voltage. The lecture also delves into transfer functions, impedance coupling in series circuits, and the propagation of changes and uncertainties. Different measurement structures like simple, push-pull, and ratiometric measurements are discussed, highlighting their advantages in eliminating sensitivity drift and offset effects. The concept of closed-loop measurements using feedback elements to reduce sensitivity drift is also explored, with examples from force and magnetic field sensors.
