Study of the decoder based on automatic dependent surveilance (ADS-B) / Wan Muhd Aiman Wan Aziz

Decoder is a digital circuit that converts input binary codes to the single numerical codes. The signal from the airplane detected by ADS-B then it contain just enough information of the plane. Before the signal pass through the decoder, it is on binary codes. Then it decode to the hexagonal. Example of the hexagonal number is 8D750291998CD728307400735727 and 8D750291998CD8283078002A6F3D. The frame rates are the frequency (rates) at which imagines device produce unique consequtive images called frame. This study was aimed to compare and investigate the relationship between the frames rates on the number of plane detected. Using the different number of frames rates, we can compare the number of plane detected with constant weather and antenna. Using the software called ADS-B scope, we can capture the plane and its position with the help of ADS-B. The type of signal can detected using the probe and the software called MultiVibAnalyse. The study found that the more frames rates used, the more plane detected. As a conclusion, the number frames rates are directly proportional the number of plane detected.
