1 KLEF University, Guntur B.Tech II year, First semester Date: PROGRAM NAME Course name Course Coordinator Course Detail : ELECTRONICS AND COMPUTER ENGINEERING : Signals & Systems : Dr.K.S.Ramesh : Theory a Lab Lecture Hours : 60 I PROGRAMME DESCRIPTION: The main objective of an engineering course in Electronics & Communication Engineering is to prove the technical viability of the new technology, together with, as appropriate, its possible economic advantages. Demonstration activities are expected to speed up the adoption of new communication techniques by reducing the techno-economic uncertainties a risks associated with innovation a, to enhance the attractiveness of new technology a its approaches in iustries a services. To analyze the ethical, social a legal issues raised by specific applications of electronics a communications in view of their being taken into account in public policy deliberations. 3 rd generation (3G) UMTS (Universal Mobile Telephone Systems) of selected topics will be promoted, particularly as regards: channel capacity a quality improvement, signal processing algorithms developments, co-channel interference strategies etc. To provide application oriented teaching with live demonstrations. To motivate the students in developing instruments a gadgets of social importance a also to design the products for real life problems. To train the students right from 2 year to make him directly fit in the iustrial a R&D environment. PROGRAMME OBJECTIVE: The programme objective can be broadly defined on five counts as below. 1. Preparation: To prepare students to excel in ECE program or to succeed in iustry /technical profession through global, rigorous education. 2.Core Competence: To provide students with a solid fouation in mathematical, scientific a engineering fuamentals required to solve engineering problems related to ECE a also to pursue higher studies. 3.Breadth: To train students with good scientific a engineering breadth so as to comprehe, analyze, design, a create novel products a solutions for the real life problems.

2 4. Professionalism: To inculcate in students professional a ethical attitude, effective communication skills, teamwork skills, multidisciplinary approach, a an ability to relate engineering issues to broader social context. 5.Learning Environment: To provide student with an academic environment aware of excellence, leadership, written ethical codes a guidelines, a the life-long learning needed for a successful professional career. After the successful completion of the Programme the students will demonstrate the following characteristics that are referred to as Programme Outcomes. II PROGRAMME OUTCOMES: a.
