Shri Bhagubhai Mafatlal Polytechnic started 03 years Diploma courses and affiliated to the Board of
Technical Examinations, Maharashtra State, in 1963. Since 1969, academic freedom was granted to the
Polytechnic, which enabled it to evolve curriculum and examination scheme and to introduce inplant training,
resulting into industry institute interaction. Thus 4 years semester sandwich pattern came in existence. Since
1978-79 academic freedom was extended to all the full-time diploma courses. In 1989-90, full autonomy was
granted to all seven full-time diploma courses. As a further development to the above, the Multi-Point Entry and
Credit System (MPE&CS) was initiated in 1981 on the progressive basis. In the scheme students can regulate
their pace of studies within the rules prescribed. From 1993-94, full academic autonomy was extended to all the
(Full Time 04 Year Sandwich Pattern)
Diploma Course in DIGITAL ELECTRONICS (Aided)
The focus of Digital Electronics course is to acquaint the students with digital circuits and their applications. The course offers Principles of Digital Techniques, C++ Programming and Microcontroller at 3rd
and 4th semester level. At 6th semester level the subject VLSI has been introduced to design and implement basic digital circuits. Signals and Systems and Control System are incorporated as elective subject. The course
on Servicing Techniques is offered to give insight in servicing and maintenance aspect of the Electronics equipment.
To make the students aware of latest development in PC Architecture and Communication engineering,
subjects like Advanced Processor Architecture, Telematics and Computer Networks are introduced at 7th semester level. The specialized subjects like Robotics and Embedded System Design are offered as Electives
out of which a student can opt for any one. Overall the students of Digital Electronics after undergoing the course will strengthen their knowledge in the circuits, communication and applications of Digital Systems
Objectives: On completion of Diploma students will be able to work as:-
Engineer in telecommunication and computer Networking and software industry
Design, implement and maintain Embedded System applications
The students receive institutional training for the first four semesters. In the 5th semester they are
given inplant/field training. They return to the polytechnic in the 6th and 7th semesters for institutional training.
In the concluding 8th semester, they again receive inplant/field training. This scheme enables the students to be
exposed to industry during the training, which is provided for practice orientation and improves their prospects

Applied Mechanics is the study of Forces and their effect on moving or stationary bodies. Also the concept of Mechanics will be useful to understand the further subjects materials & structures, analysis of
structures and design.
Students will be able to: (1) Understand the force / force system and their effect on a body.
(2) Apply the concept of mechanics to the real situation. (3) Build the pre-requisite of higher semester subject related to designs.
