Continue until the next step is to place components

Portable Audio Equalizer Marketing Requirement s Engineering RequirementsJustification 1, 2, 4 1. The total harmonic distortion should be <0.1%. Based upon competitive benchmarking and existing amplifier technology. Class A, B, and AB amplifiers are able to obtain this level of THD. 2, 4 1. Should have three band equalization Achievable with few components and very popular 3 - A 1. Weight should not exceed 1 pound User will have to carry it while walking

Portable Audio Equalizer 3-B1.The dimensions should not exceed 2” x 2”x 1”. Unit will interconnect with existing equipment 4-A1.Production cost should not exceed $15. This is based upon competitive market analysis and previous system designs. Objectives 1.The system should have excellent sound quality. 2.The system should have easy equalization 3.The system should be of light weight 4.The system should be low cost Constraints A.The system must be portable B.The system will be an add-on to existing MP3 player
