ASSESSMENT OF COURSE OUTCOMES




After the completion of the course, the course outcomes assessment is evaluated using the

following methods

i. Mid Exams,

ii. End Exams, and

iii. Course End Survey (by feedback)

I. Mid exams: The weightage of mid marks for 25 consists of subjective (descriptive) – 15,

objective -10 (Conducted by university through on line system at College level with 20

Multiple choice questions with a weightage of 0.5 Mark each). The objective examination is

for 20 minutes duration. The subjective examination is for 120 minutes duration. Each

subjective type test question paper shall contain 4 questions and all questions need to be

answered. The Objective examination marks10, and subjective examination marks 15 added

for finalizing internal marks 25. The better of the two tests will be taken for internal marks.

As the syllabus is framed for 8 units, the 1st mid examination (both Objective and Subjective)

is conducted in 1-4 units and second test in 5-8 units of each subject in a semester.

SAMPLE QUESTIONS:

Subjective-I

pass filter characteristic with 0.5db ripple in the pass band? In the pulse repetition

frequency is 10KHZ, calculate the maximum unambiguous range?

2. a. Draw the block diagram of IF Doppler filter bank? Draw its frequency response

characteristics?

to radar is 50 knots at a transmitted frequency of 80MHZ.

3. a. What is a delay line canceller? Illustrate the concept of blind speeds based on the

frequency response of a single delay line canceller. Discuss the factors limiting the

performance of an MTI system.

a. Auto-covariance. b. Cross-covariance c. Autocorrelation d. Cross-correlation.

The evaluation of attainment of COs in MID exams is conducted and percentage of

attainment of CO is benchmarked as a minimum of 40% in mid exams as per the Quality

Assessment Committee of the institution.

The percentage of attainment of CO for internal examinations is shown in Table 1.1 and

corresponding graph is shown in Fig 1.1.

II. End Exams: The end semester examination is conducted by university at college covering

the topics of all units for 70 marks.

Part: A contains a mandatory question (Brainstorming / Thought provoking / case study) for

22 marks.

Part: B has 6 questions (One from each Unit). The student has to answer 3out of 6 questions

in Part – B and carries a weightage of 16 marks each.

The evaluation of the attainment of CO is conducted on the basis of University semester end

examination as shown in Table 1.2 and corresponding graph is shown in Fig 1.2.
