Slide 2: 

Analog Communication. (9073)

Teaching and Examination Scheme : 

Teaching and Examination Scheme Teaching scheme- Th-2 hrs Pr-2 hrs Examination scheme-Th-80mks Tm-20 mks Tw-25 mks

Rational : 

Rational Communication plays vital role in our lives. Development in communication technology have increased its pplications in allied fields of electronics including satellite, mobile,RADAR, telephony, telegraphy, industrial controls, etc. It is the technology subject which expert the student to understand the operation and fault finding of AM & FM transmitter, AM & FM radio receiver & identifying different antennas.

Objectives : 

Objectives The student should able to 1. Classify different types of communication system. 2. Explain electromagnetic spectrum. 3. Describe amplitude modulation & its types. 4. Identify different section in radio receiver. 5. Troubleshooting AM / FM radio receivers 6. To describe FM. 7. Compare AM & FM. 8. Describe different parameter of transmission line and their radiation pattern. 9. Describe different types of wave propagation and their application.

Learning structure : 

Learning structure Applications Troubleshooting and Servicing skills of AM and FM radio receiver To Understand the Transmission and Reception Procedure Block Diagram of AM and FM Transmitter / Receiver Principle Transmitting and Receiving Antennas, Transmission Lines and Wave Amplitude modulation ( High level and low level modulation) Frequency modulation (Armstrong Method) AM Receiver FM Receiver
