Scientific equipment and services and techno instruments are both iso 9001: 2000 certified company engaged in manufacturing of complete laboratory experiments measuring instruments for bs and ms laboratories of physics, electronics and electrical engineering.
The company manufactures laboratory control instruments.
Digital control systems have become very important today because of the advantages it offers and the increased availability of inexpensive computing power of microprocessors. The principal advantages include fixed hardware with complete software flexibility and the feasibility of implementing integration and differentiation on extremely slow varying signals. On the other hand digital controllers have some drawbacks also such as errors due to the processes of sampling and reconstruction, computational errors caused by finite wordlength, truncation, register overflow, as well as the de-stabilization effects of sampling. A clear understanding of all these aspects is of great value to a student of control engineering.
