Abstmct-The problem of designiiag orthonormal (paraunitary) filter banks has been addressed in the past. Several structures have been reported for implementing such systems. One of the structur es reported imposes a pairwise mirror-image symmetry constraint on the frequency responses of the analysis (and synthesis) filters around 7r/2. This shveture requires fewer multipliers, and the design ti...

Relationships between chiroptical properties (Optical Rotatory Dispersion, ORD, and Circular Dichroism, CD) and Conformation of structur— ally simple isotactic polymers and copolymers derived from optically active monomers are reviewed. Both experimental and calculated values fit with chain cotiformations consisting prëdomirantly of one screw sense helical sections due to dissyinmetric cooperat...
