We ' ve known the product ' s surface requirement ( etching, shine - sided, mirror - sided, oil - spraying, electroplating, transparence, etc. ), material, quantity ratio ( quantity of the same part in a product ) and output from customer
我們從客戶那知道產品的表面要求(蝕紋,亮面,鏡面,噴油,電鍍透明等) ,材質,用量比(同一個零件在一個產品中的數量) ,產量。 -
We propose a chaos - based generation of the random ppm - ps signals, design and implement a generator of the ppm - ps signals. we introduce an if sampling technique and simulate the performances of digital demodulation techniques of using hilbert filters, sine filters, bessel filters and poly - phase filters. the poly - phase filtering method can achieve the higher mirror - frequency rejection ratio by using the low order filters
介紹了中頻采樣技術,並對希爾伯特濾波法、辛格內插函數修正、貝賽爾函數插值法及多相濾波法等數字解調演算法進行了計算機模擬和性能比較,指出多相濾波法能以較低的階數實現較高的鏡頻抑制比。
