Signal Processing Device and Method, Signal Processing Program, and Recording Medium Where the Program is Recorded |
摘要 |
There is provided a new signal processing device that uses functions appropriate to signal properties to acquire high-quality signals. The signal processing device includes a sampling circuit 2 that samples an input signal and outputs a discrete signal, multiple function generators 3 that generate multiple sampling functions with parameters m different from each other, plural inner product operating units 4 for each of the parameters m that take an inner product between the input signal and each of plural sampling functions and output an inner product operating value, and a judging unit 8 that determines parameter m providing a minimum error out of multiple errors composed of differences between the sampling value and inner product operating values output from the multiple inner product operating units and outputs the parameter m signal. The signal processing device outputs a discrete signal composed of a string of the sampling values and the parameter m signal.
