5. Operational Amplifiers Introduction In many electronic circuits‚ the signals (voltage differences) that are generated and manipulated are very small. Therefore‚ amplification is often essential. When playing a CD for instance‚ the signals generated in the CD player are quite small and will not adequately drive a speaker system. The signals from the CD player are therefore passed into the stereo amplifier (which often comes as a tuner/amplifier combination in modern home stereo systems)

business scope; specifically‚ Best Buy and the once flourishing‚ Circuit City. Portions of this report will touch on the economical reasons that both had placed the blame for their decision to downsize. Another aspect that was reviewed as a reason for downsizing is the lack of innovation. Being that‚ both companies failed to adapt to the fast-evolving electronics industry and online retail competition. Our reasons will expose why Circuit City folded and why Best Buy will more than likely follow. We
