Basic Electronics Laboratory
General information about the Laboratory: This is a first level laboratory in which students are introduced with Electronics & Communication Engineering for the first time and are trained with preliminary of Electronics. This Lab is used in odd (1st) and even (2nd) both the semesters. Students of ECE,EE,AEIE and CSE,IT,ME,CE departments are using this lab in 1st and 2nd semesters respectively. More than eight setup are available. No of students per setup are in general four.
Before starting of the laboratory the students are instructed with necessary safety and precautionary measures that has to be adopted in any electrical laboratory. Well designed laboratory manual / instruction sheets are provided to students at the beginning of the session for a particular lab. Laboratory is maintained and conducted by well trained technical supporting staff under the supervision of the faculty members. Most of the technical staffs have undergone first aid and fire fighting training.
