چکیده
This paper presents a new method for signal reconstruction by leveraging sampled-data control theory. We formulate the signal reconstruction problem in terms of an analog performance optimization problem using a stable discretetime filter. The performance criterion naturally takes intersample behavior into account. We present methods for computing optimal solutions which are guranteed to be stable and causal. Detailed comparisons to alternative methods are provided. We discuss some applications in sound and image reconstruction.

متن کاملA Novel Approach to Repetitive Control via Sampled-data H Filters
A new paradigm of digital signal processing has recently been proposed in view of sampled-data control theory. This filter, called sampled-data H∞ filter, approximates a linear phase characteristic in continuous-time domain, that is, a pure delay. By this property, we propose a new repetitive controller including the sampled-data H∞ optimal filter. Moreover, to achieve the stability, we introdu...
متن کاملStability of Signal Reconstruction Filters Via Cardinal Exponential Splines
There is a new trend in digital signal processing. It is gradually recognized that while the processing is done in the digital domain, its performance must be measured in the analog domain. This framework was proposed by the present authors and co-workers, and also recently proposed by Unser and his co-workers. While our approach relies on modern sampleddata control theory which minimizes an an...
