6-band low cost graphic equalizer / Azan Aminnudin Mahmad Nor and Faizal Din

A graphic equalizer is a device dial is connected to an amplifier in order to improve quality of the sound produce. Graphic equalizer come in several type, the type is determined by how many band it consist. Graphic equalizers that are available in market these days, range from 4 -band to 16-band. Each band is assigned with different range of frequency that is control by a variable resistor, each band gives different effect to the sound produce. This project is a 6-band graphic equalizer built at the lower cost possible Ibis graphic equalizer is really cheap since it only cost about half the cost of readymade graphic equalizer. Graphic equalizer used to be build using LC tuned coil/inductor circuits, which take space and more prone to noise pick-up, so this graphic equalizer is built around two ICs in order to solve these problem and make if a lot cheaper
