Title:
フィルタ係数算出装置を備えた信号発生装置及び信号発生方法
Document Type and Number:
Japanese Patent JP6661866
Kind Code:
B2
Abstract:
A filter coefficient calculation device includes a function unit that has a plurality of functions to be executed by an FIR filter, a function selection unit that selects one or a plurality of functions from among the plurality of functions, and a filter coefficient calculation unit that calculates a filter coefficient in the selected one or plurality of functions, and is configured such that the function unit includes a first transfer function calculation unit, a second transfer function calculation unit, and a third transfer function calculation unit which calculate a transfer function of the FIR filter in the respective functions, and the filter coefficient calculation unit performs inverse Fourier transform on the transfer function in the selected one function or a product of the transfer functions in the plurality of functions to obtain an impulse response of the FIR filter and calculates the impulse response as the filter coefficient.
