Application of DSP

In this experiment, I reviewed a patent which describes digital signal processing filters to improve loudspeaker transient response.The field of invention relates to loudspeakers , specifically to loudspeaker system including digital signal systems. I learnt that to improve the loudspeaker response, a six step process is used.The process begins with identifying a substantially linear, time-invariant, and spatially-consistent loudspeaker mechanism causing transient response distortion. After

characterizing the identified mechanism. Next step is to determine the characterized

mechanism's two-port response. It is important to establish a target response for the

characterized mechanism. This is followed by calculating an ideal filter to achieve the target

response. This leads to designing a cost-reduced filter based on the ideal filter to thereby form a

loudspeaker mechanism algorithm (LMA) filter.
