Abstract

Of late, signal processing is having an impact on a wide range of applications, from general radio signal processing and transmission to sophisticated biomedical applications. Despite not being as popular as its digital counterpart, analog signal processing has great applications in sound signal processing, noise elimination, biomedical signal processing and provides a cheap and effective alternative to digital signal processing. This paper proposes an application of analog audio signal processing for entertainment. The proposed design includes splitting of the audio spectrum by 2 nd order Chebyshev filters into eight distinct spectra, processing of the spectrum and visually implementing them on a twelve storied building in realtime using Christmas lights. This is an exemplary work of application of analog signal processing using analog circuitry in the entertainment industry.
