DIGITAL CIRCUIT, OSCILLATOR, ELECTRONIC APPARATUS, MOBILE BODY AND SIGNAL PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2020025154
Kind Code:
A
Abstract:
To provide a digital circuit capable of achieving a filter which can handle input data of floating point format.SOLUTION: The digital circuit executes integral calculation of integrating input data, executes differential calculation of determining a difference between first data obtained by the integral calculation against an integer N of at least one and second data obtained at N previous cycles of the first data by the integral calculation, initializes the integral calculation each time the input data at N cycles is input and corrects third data obtained by the differential calculation on the basis of the first data.SELECTED DRAWING: Figure 1
