STIFとは 意味・読み方・使い方

In a mixer 104, frequency conversion (1^stIF) of each of L1, L2C, and L5 through E5a signals is performed by mixing it with a local oscillation signal, whereby the frequency of the L1 signal and the frequencies of the L2C and L5 through E5a signals become in a mutually image relation.例文帳に追加

ミキサ１０４において、Ｌ１、Ｌ２Ｃ及びＬ５・Ｅ５ａの各信号を、Ｌ１信号の周波数と、Ｌ２Ｃ及びＬ５・Ｅ５ａ信号の周波数とが互いに影像関係となる局部発振信号と混合して周波数変換（１^stＩＦ）する。 - 特許庁
