The optimization of bandlimited systems

Bandlimited functions play important roles in the design of signal transmission systems; antennas; digital, analog, and optical filters; tapered transmismon lines, etc. The basic problem arising in all the above-mentioned applications consists in approximating a given nonbandlimited response with a bandlimited system function. This paper presents 1) a unified treat-merit of the mathematical properties of bandlimited system functions; 2) analytical and numerical methods for the optimization of bandlimited systems; and 3) the application of the theoretical results to practical engineering problems.
