本文通過分析認為，當信號集中的任一信號可表示為一系列已知信號的線性代數和時，信號集便構成可分解信號集，已知信號稱為基波信號；對可分解信號而言，基波系數構成一序列，當對指定的基波信號集分解唯一確定時，系數序列本身便是信號的一個表示；可分解信號采樣定理指出當基波樣值矩陣的秩等於基波數時，則由采樣點處的采樣樣構成的樣值序列必與基波系數序列一一對應，從而由該樣值序列構成的采樣必為完全采樣；可分解信號采樣定理中的推論指出，對信號集進行采樣，采樣頻率必須大於其信號分解的基波數與其對應時長之比；對有限帶寬信號，若基波信號為正弦信號時，由可分解信號采樣定理推論給出的結論與經典采樣定理一致。Wenzhou cilotus beauty implements co., ltd is the leading manufacturer exporter of beauty care tools in china, establish in 1994, we deal with all kinds of business forms including custom designs and oem production. among our customers are avon, revlon, o - bey, solingen, kiss etc. we produce nail files, emery boards, foot fles, callous removers, nail buffers, buffer block, nail shine, glass nail files, nail brush, nail tips, nail clippers, tweezers, scissors
