• Analyze and design controlled rectifier, DC to DC converters, DC to AC inverters and SMPS.
• Define instrument errors.
• Develop circuits for multirange Ammeters, Voltmeters and Bridges to measure passive component values and frequency.
• Describe the principle of operation of Digital instruments and PLCs.
• Use Instrumentation amplifier for measuring physical parameters.
Question paper pattern:
• Examination will be conducted for 100 marks with question paper containing 10 full questions, each of 20 marks.
• Each full question can have a maximum of 4 sub questions.
• There will be 2 full questions from each module covering all the topics of the module.
• Students will have to answer 5 full questions, selecting one full question from each module.
• The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
