Computer usuage
To carry out AM and FM modulation experiments using discrete electronic components, Software’s like MATLAB and PSPICE are used to simulate the circuit operations
Hardware Laboratory Usage
Each laboratory station is equipped with breadboards, a power supply, CRO and Function generators. Students work in groups of three, but maintain individual laboratory notebooks and submit individual records.

Laboratory Policies and Record Format
Records are due at the beginning of the lab period. The records are intended to be a complete documentation of the work done in preparation for and during the lab. The record should be
complete so that someone else familiar with Electronic design could use it to verify your work. The pre-lab and post-lab record format is as follows:
- Each student should bring a hardcopy of lab manual (which will be forwarded by the corresponding staff in-charge) for the scheduled lab experiment, with pre-lab questions filled and relevant tabular columns drawn. The observations entered in this printout have to be attested and marks should be awarded during that lab period itself.
- Lab record for current session has to be submitted during the next session itself. Faculty should award the marks for record and has to sign the coversheet as well as index page during that session itself. Lab records should be submitted on the record sheets provided from the university. Your record is a professional presentation of your work in the lab. Neatness, organization, and completeness will be rewarded. Points will be deducted for any part that is not clear.
- In this laboratory students will work in teams of three. However, the lab records will be written individually. Please use the following format for your lab records. a. Cover Page: Include your name, Subject Code, Section No., Experiment No. and Date.
b. Objectives: Enumerate 3 or 4 of the topics that you think the lab will teach you. There should be one or two sentences per objective. Remember, you should write about what you will learn, not what you will do. c. Design: This part contains all the steps required to arrive at your final circuit. This should include diagrams, tables, equations, K-maps, explanations, etc. Be sure to reproduce any tables you completed for the lab. This section should also include a clear written description of your design process. Simply including a circuit schematic is not sufficient. d. Questions: Pre-lab questions should be answered in the print-out of lab manual itself. Post-lab questions should be answered in Lab record sheets. Answers should be written formally.
- Your work must be original and prepared independently. However, if you need any guidance or have any questions or problems, please do not hesitate to approach your staff in-charge during office hours. The students should follow the dress code in the Lab session.
- Each laboratory exercise (circuit) must be completed and demonstrated to your Staff In- charge in order to receive working circuit credit. This is the procedure to follow: a. Circuit works: If the circuit works during the lab period (3 hours), call your staff in-charge, and he/she will sign and date it.. This is the end of this lab, and you will get a complete grade for this portion of the lab. b. Circuit does not work: If the circuit does not work, you must make use of the open times for the lab room to complete your circuit. When your circuit is ready, contact your staff in-charge to set up a time when the two of you can meet to check your circuit.
- Attendance at your regularly scheduled lab period is required. An unexpected absence will result in loss of credit for your lab. If for valid reason a student misses a lab, or makes a reasonable request in advance of the class meeting, it is permissible for the student to do the lab in a different section later in the week if approved by the staff in- charge of both the sections. Habitually late students (i.e., students late more than 15
