INTRODUCTION
ALL INDIA RADIO (AIR) is a national service planned, developed and operated by the PRASAR BHARATI BROADCASTING CORPORATION of INDIA.
All India Radio stations spread throughout the nation ,relay programs originating from Delhi.
The Radio Networking terminal located at AIR stations receive S-Band or C-band transmissions.
PROCESS OF BROADCASTING
The complete process of broadcasting is divided in 3 blocks:-
Modulation
Transmission
Reception
DIGITAL MODULATION
Digital communication is advantageous over Analog in three aspects:
Bandwidth Efficiency.
Cost Efficiency.
Power Efficiency.
With the introduction of digital communication techniques in broadcasting and sophisticated modulation schemes we can transmit high quality programs faster and within very less bandwidth.
POWER SUPPLY SYSTEM
The power supply authority is generally responsible for the maintenance of the service line carrying H.T or L.T. supplies to installation. This may include the supply transformer.
STL TRANSMITTER CONSISTS OF
Single Audio Input Transformer(LT).
The Base Band Unit Consists of:-
Music Amplifier(AT).
Base Band Interface Unit(GT).
Radio Frequency Unit.
Antenna Change Over Unit.
Low Loss Cable.
DC Power Supply(DC).
Monitoring(CM) And Alarm Interface Unit(AL).
Logic(LO) And Parameter Control Card(PC).).
STL RECEIVER CONSISTS OF
Receiving Antenna.
Antenna Filter And RF Hybrid Divider Unit.
RF Receiver Unit
The Base Band Unit-It Consists of
Base band interface unit(GR).
Music amplifier(AR).
Muting Switch(AS).
Single Audio Line Transformer.
DC Power Supply Units.
Monitoring(CM) And Alarm Interface Unit(AL).
Logic (LO) And Parameter Control Card(PC).
MEASUREMENTS ON STL
Frequency Response
Distortion
Signal to Noise Ratio
AIR CONDITIONING
The Primary Function of an Air conditioning System is to maintain Conductive conditions for human comfort.
Comfort Air Conditioning is the Process by which simultaneously in the temperature, moisture contents, moments and quality of air in enclosed spaces, intended for human occupancy may be within required limits.
A complete Air Conditioning performs the following functions-
Cooling and Dehumidification.
Heating and Humidification.
Air Filtration and Proper Ventilation.
These functions involves control of Temperature, Humidity, Purity and the Moment of Air.
Air Conditioning System can be divided as-
DX Type system
Chilled Water System
