一種內(nèi)插器,特別是在計(jì)量裝置中和光柵一起使用,用于檢測(cè)位置,它接收正交的輸入信號(hào). An internal interpolator, particularly in the metering apparatus and used with the grating, for detecting the position, which receives the quadrature input signal. 對(duì)輸入信號(hào)中的一個(gè)進(jìn)行平方并把兩個(gè)輸入信號(hào)乘在一起, 以提供頻率為輸入信號(hào)頻率二倍頻的進(jìn)一步的正交信號(hào). Of an input signal is squared and the two input signals are multiplied together to provide a frequency of the second harmonic of the input signal frequency quadrature signal further. 也對(duì)進(jìn)一步的信號(hào)進(jìn)行平方,并把進(jìn)一步的信號(hào)乘在一起,以提供頻率為輸入信號(hào)頻率4倍頻的輸出信號(hào).
