DESIGN AND ANALYSIS OF LOW SPEED DIGITAL TRANSCEIVER CIRCUIT THROUGH RADIO FREQUENCY (VHF BAND)

The rapid growth of technology has drastically changed the communications
technology. To meet the present day technology needs, data transfers at higher
speeds are to be achieved which is possible by Radio Frequency (RF)
communication. Transmission through Radio Frequency is another option of wireless
communication that utilizes effective radio frequency, other than hand phone and
Internet resource. Communication through radio is unique and has its own extras.
Hence this project intends to design low speed digital tranceiver circuit trough RF,
user can send the texts, folder and graphic to user that has same equipment in another
station depending on the transceiver. Besides, it is also possible to transmit a voice
with the use of handy talkie. This project is important especially when it comes to
lack of telecommunication signal, like no Internet connection, outside Bluetooth
range, no coverage for mobile phone or when travelling in the mountain and forest
where there are places that don't have a facility for communication.
