Perfect Reconstruction Digital Crossover Exhibiting Optimum Time Domain Transient Response in All Bands

Document Thumbnail

A crossover architecture is described that combines the optimal transient characteristics of the Gaussian filter with the perfect reconstruction characteristic of the matched-delay subtractive filter structure. Issues of implementation, including the computational burden associated with finite impulse response (FIR) filters, are discussed and viable infinite impulse response (IIR) approximations are presented.
