If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
You often use negative feedback to control the output of a process. Examples range from temperature and flow control in oil refineries to simple operational amplifiers. You use negative-feedback ...
In addition, since all waveforms are constant-valued at equilibrium points, and so capacitors act as open circuits and inductors act as short circuits. There in lies the basic algorithm for computing ...
