About NPTEL Basic Electronics Course:
The course is about basic electronic circuits, both analog and digital. In the analog part, diode circuits, BJT amplifiers, Op Amp circuits will be covered. In the digital part, combinatorial and sequential circuits will be covered. A unique feature of the course is extensive use of circuit simulation results in order to give a realistic picture of the circuit operation and waveforms. Assignments are designed to help the students to test their understanding of the concepts being covered. A circuit simulation package will be made available (as free download) to enable students to simulate circuits covered in the course and gain further insight in their functioning.

CRITERIA TO GET A CERTIFICATE:
Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
