Feedback Systems

Feedback Systems process signals and as such are signal processors. The processing part of a feedback system may be electrical or electronic, ranging from a very simple to a highly complex circuits. Simple analogue feedback control circuits can be constructed using individual or discrete components, such as transistors, resistors and capacitors,…

Open-loop System

In the previous tutorial about Electronic Systems, we saw that a system can be defined as a collection of subsystems which direct or control an input signal to produce the desired output condition. The function of any electronic system is to automatically regulate the output and keep it within the…

Closed-loop Systems

Systems in which the output quantity has no effect upon the input to the control process are called open-loop control systems, and that open-loop systems are just that, open ended non-feedback systems. But the goal of any electrical or electronic control system is to measure, monitor, and control a process…
