Introduction According to Norbert Wiener, the American mathematician and the father of cybernetics, feedback is a method of controlling a system by reinserting the results of its past performance into it. In a feedback system, a signal that is proportional to the output is fed back to the input and combined with the input signal […]

Introduction A linear circuit is one whose output signal is linearly proportional to its input signal. As a simple case, it is possible to model the network at only two terminals as shown in Figure 1. Here, only V1 and I1 as the voltage and the current internal to the circuit, need to be described. […]

STMelectronics introduces a super tiny two-axis gyroscope (L20G20IS), a Micro-Electro-Mechanical system (MEMS) designed for the optical image stabilization for Smartphones with less energy consumption compared to its predecessor (L2G2IS). A gyroscope, or gyro for short, adds an additional dimension to the information supplied from the accelerometer by tracking rotation or twist. An accelerometer measures linear acceleration of movement, while […]
