The common mistakes done by students in CAT 3:

Signal generator is used in square wave generation circuit 
Signal generator is used in RC phase shift oscillator
Clippers are explained without op-amp (But oscillator circuit written using op-amp).

Take care of such things in the main Exam. Wish you best of luck for u r main exam.

Final Internal Marks

I wish you Best of Luck for your CAT 3 as well as for main exams. For any discussion you are most welcome. Now give highest priority to your studies. 

Quiz will be conducted in the next week (Between 29 April to 3 May) 
                  [Complete syllabus and basics]

All the students are here by informed to submit the soft copy of the report to the student representatives. Student representatives are supposed to submit to me when i come to the class on Monday 15/03/2013 without fail.

Lab Experiments: 
For most of the experiment circuit diagram, theory, procedure, nature of input, nature of output, Tabular column, lot many such information is given. Students can try their own circuit/ Design...for the following experiment. 

1.      Schmitt Trigger Experiment

a.      There is a need of circuit which detects whenever input signal exceeds some positive and negative voltages (both are same voltages). Conduct an experiment for the same. Derive the necessary equation.

b.      There is a need of circuit which detects whenever input signal exceeds some positive and negative voltages (both are not same voltages). Conduct an experiment for the same. Derive the necessary equation.

2.      DAC Experiment: Design a Digital to analog converter (DAC) the input is four bits (0000 through 1111 any combination) the output of the circuit should be analog voltage. Derive the necessary equation. ( use R-2R ladder network)

Many students have participated in Insignia’13. You all can take rest on Sunday. The LIC assignment deadline is extended up to 26/03/2013.
