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.

摘要： A signal processing device and a signal processing method are provided which can reproduce a smooth signal in the reproduction of a discrete signal having a non-uniform sample point interval. The device includes a coefficient calculation unit 4 that inputs a sample point signal E2 representative of the time of a sample point of a discrete signal E1 having a non-uniform sample point interval to obtain a coefficient of a sampling function corresponding to the discrete signal, and a reproduction signal calculation unit 5 that obtains a continuous reproduction signal E3 by calculating and outputting a function value within the sample point interval from the discrete signal and the value of the coefficient outputted by the coefficient calculation unit.
