- 2. Introduction ➢ FM is widely used in communication systems. ➢ This circuit is designed to implement the signal modulation and demodulation process. The modulation and demodulation of the signal plays an important role in the communication system. ➢ The design uses MATLAB integrated environment M files to prepare the formula in order to achieve FM modulation and demodulation process. ➢ In radio communication, Frequency modulation (FM) is the method of conveying information over a carrier wave by varying its frequency. ➢ Today simulation is an important domain which attracts many researchers from several fields and disciplines

Literature Review Sr. No. Publication year Name of Authors Title of Paper Features provided 3. 2020 Jay Mistry Simulating modulation & demodulation techniques in MATLAB Modulation is widely used as it improves the quality of reception and transmission, increases the range of communication, reduces the antenna dimensions, and less interference from other signals. 4 2019 Oborkhale Lawrence, Iroegbu Chibuisi Modelling and Simulation of Frequency Modulated Radio Channel Using Matlab and Simulink This research presents a step by step approach in modelling and simulation of Frequency Modulated (FM) radio channel using MATLAB and SIMULINK. The results obtained from the simulated models prove the capability of MATLAB and SIMULINK as a tool for adequately predicting performance and behaviour.
- 5. Modulation And Demodulation Modulation is the process of converting data into electrical signals. Demodulation is getting the original form of data modulated carrier wave.
- 6. Working ➢ At the transmitting end of the communication system, the spectrum of the baseband signal is shifted (modulated) into the frequency range suitable for channel transmission. This is the process of modulation. ➢ After the signal is transmitted through the channel, the receiving end with the signal amplification and inverse conversion function moves (demodulates) the modulated signal to the original frequency range. This is the demodulation process.

- 9. Conclusion ➢ In this research, we have demonstrated the basic utility of MATLAB as a modeling and simulation tool using modulation/demodulation methods as case studies. ➢ We carried out this study in the context of a FM modulated channel. MATLAB have got rich libraries and built-in functions that can be used to ease the whole modeling process.
