GSM has been around for at least two decades now. Being such a robust cellular network system, the current networks are still based on it. Living in the information age; almost everyone has a cell phone, may it be a basic phone or a smart phone. This project focuses on the design of Android terminal, the communication between PIC and GSM module, the realization of the wireless module device¿s driver, the difficulty in supplying the appropriate low-voltage DC for MCU and wireless module just by a single live wire. The users can manipulate appliances anytime, anywhere, letting our houses become more and more automated and intelligent. Conventional mechanical switching of household electrical appliances is location bound. The system makes switching boundless within the Bluetooth 10m coverage. Now with your android phone in any relaxing position at home user can switch 'ON' and 'OFF' virtually all home electrical powered appliances.

The indispensable need for alignment and optimization of sound systems has prompted this study. It tries to answer questions such as: What constitutes audio and frequency response components? Are they pragmatic? What are filters in this context?The work mainly focuses on improving an input audio signal to be free from shape glitch in order to circumvent unwanted audible peaks or anomalies in the final sound. Additionally, this study tries to offer operational flexibility per definition of an Audio Multitone Refiner. Because of their versatility, the signal analyzing tools Laplace transform, Fourier series, D.C. and transient analysis were employed to ascertain the realization of all constructed circuits in this study. 'Casio fx7400G' language was used during programming of the band pass filter, as were active filters.
