linear phase FIR filterとは 意味・読み方・使い方

The FM demodulator uses a plurality of filter coefficients of linear phase FIR (Finite Impulse Response), and performs band control by switching filter coefficients of band limiting digital filters.例文帳に追加

複数の直線位相ＦＩＲ型のフィルタ係数を用い、帯域制限デジタルフィルタのフィルタ係数を切り替えて帯域制御を行う。 - 特許庁

Frequency characteristic information in response to an instruction input accepted through a parameter input section 14 is formed by an infinite impulse response (IIR) filter 15 and on the basis of the frequency characteristic information, an FIR filter coefficient calculation section 16 calculates an FIR filter coefficient having the same amplitude characteristics as those of the frequency characteristic information, so that the phase characteristics become linear characteristics.例文帳に追加

パラメータ入力部１４を通じて受け付けた指示入力に応じた周波数特性情報をＩＩＲフィルタ１５により形成し、この周波数特性情報に基づいて、ＦＩＲフィルタ係数算出部１６により、当該周波数特性情報と同じ振幅特性を有し、位相特性が直線特性となるようにするＦＩＲフィルタ係数を算出する。 - 特許庁
