- Analog And Digital Circuits For Electronic Control System Ap
Digital circuits deal, in principle, with only two values of voltage, whereas analog circuits process signals with continuous variation of voltage. In fact, of course, no macroscopic signal is truly quantized, so even a digital circuit designer needs some familiarity with analog electronics. These notes will provide a very basic introduction to the capabilities of analog circuitry. You may also need to review the elementary analysis of passive DC and AC circuits as found in a freshman physics text. In system design, there is, and has been, a continuous need to sense real-world analog quantities (such as temperature, pressure, or humidity), make computations with them, and then perform some action with the result. In today’s systems, the computations need to be made at increased speeds and the accuracy with which the computations must be made, even as the speed increases, must be the same or higher as time progresses. The advent of the microcontroller, and its extensive use in all types of control applications, many of them battery powered, has led to new control system design approaches. Rather than computing using analog quantities, the analog quantities are sensed, conditioned, and converted to digital, processed digitally, and then converted back to an analog output, which is then used to perform the necessary output action. This practical textbook covers the latest techniques in microcontroller-based control system design. It is aimed at engineering students and engineers new to working with microcontrollers. The book provides a clear, scientific and technical understanding of this subject. The information contained herein will equip the readers with latest and up-to-date knowledge. Examples such as digital and analog circuit applications, field-effect transistors, and operational amplifiers provide the platform for modelling of active devices, including large-signal, small-signal (incremental), nonlinear and piecewise-linear models are given in this book.
