negative phase wave
解釋
負相波-
First, we calculate out the zero point in a simple numeral method, then we get the phase according to the fact that the symbol of phase changed is opposite in the positive - slope and the negative - slope of triangle wave. this method has the following characteristics : easy to calculate, simple to realize and high precision
首先用簡單的數值方法較準確的計算出零點時刻;進而根據三角波掃頻時正程和逆程相位變化符號相反的特性,巧妙的完成了相位計算,該方法具有計算簡單、實現方便、準確度高等特點。
