DIGITAL SIGNAL PROCESSING & CONTROL SYSTEM LAB

Digital Signal Processing and Control System Lab abbreviated as DSP & CONTROL Lab is employed for the under-graduate students of our college. The post-graduates use it as a Project Lab while the under-graduates utilize it for working with MATLAB R2023b and DSP processor .This lab is facilitated for the students in their fourth semester as Control System and Instrumentation Lab and fifth semester as Digital Signal Processing Lab.

Safety Measures

1. Do not use highly flammable liquids near electrical equipment.
2. Do not bring any edibles and water bottles in the lab.
3. Never plug leads into the power source unless they are connected to an established circuit.
4. Avoid contacting circuits with wet hands or wet materials.
5. Check circuits for proper grounding with respect to the power source.
6. In case of fire, use the nearest available fire extinguisher.
7. Never change wiring with the circuit plugged into the power source.
8. Work on electrical devices should be done only after the power has been shut off in such a manner that it cannot be turned on accidentally.
9. If the power cannot be turned off, use only one hand when working on it. This will prevent a circuit from going through your heart, which could be potentially fatal.
10. Internal energy storage devices such as capacitors must be discharged.
11. Use only tools and equipment with non-conducting handles when working with electrical devices.
