91. Feedback system (Part-B)
The chapter covers the configurations of feedback systems with a focus on voltage and current signals, samplers, and mixers. It explains the ideal conditions necessary to minimize loading effects and the significance of resistance values in feedback networks. Different naming conventions for feedback configurations are also introduced, emphasizing their impact on system behavior.

What we have learnt
- Feedback systems can be classified based on the types of signals and their connections.
- Ideal conditions such as infinite input resistance and zero output resistance enhance performance by minimizing loading effects.
- Naming conventions are vital for correctly identifying configurations and their impacts on system characteristics.
Key Concepts
- -- Feedback System
- A system that uses its output to influence its input in order to maintain the desired output.
- -- Voltage Sampling
- The process of measuring voltages at the output port, which influences the feedback signal.
- -- Current Mixing
- The process of combining current signals from multiple sources before transmission through the system.
- -- Shunt and Series Connections
- Configurations used in feedback systems to describe how signals are sampled and mixed.
- -- Desensitization Factor
- A factor that quantifies how feedback can modify the input and output resistances of a feedback system.
