dc.description.abstract | Frequency Modulation has been part of our daily lives and has been used for many decades. Invented by Edwin H. Armstrong in 1933, it has played an important role in communication technologies. Hence, it would be interesting to go inside the invisible waves that travel along in our everyday lives and understand the importance of this technology. This project will demonstrate the process of modulation and demodulation. This project will also showcase the effect of frequency deviation and study the negative effects of noises. This project will utilize a device called HackRF to transmit and receive the signal, and also using software named Gnu Radio to configure the settings. Using two HackRF, a known clear undistorted sound clip was transmitted over the air from one HackRF to the other, using two different frequency deviations to simulate wideband and narrowband. It was found that white Gaussian noise can be heard when a small frequency deviation value of 500Hz was used. The noise was absent with a large frequency deviation value of 50kHz. The result was observed and analyzed on Gnu Radio in Time and Frequency domain with intermediary waveforms to observe stages of modulation and demodulation. With these experiential results, it further aids the understanding of modulation and demodulation process. | en_US |
