Consider the system shown in Figure A2 – 1: R(s) Y(s) K g2 + 3s + 2 Figure A2 - 1 (a) Assuming that Kis a constant gain, determine the type of the controller used in this syste and discuss its main characteristics. (b) Determine the value of K that will give a 10% steady-state-error for a step input. (c) Analyse the response of the open loop system P(s) = 1/ (s2+3s+2) showing its natural frequency, gain and damping ratio.
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
