  2. The signal we named it fundamental wave ; according to the fundamental wave, coefficients of the fundamental wave can be lined in a sequence. when the unique of the dissolve of the fundamental wave can be confirmed, the sequence of the coefficients can be regarded as one of representation forms of the signal itself ; theory of dissolvable signal shows that when order of the matrix of fundamental wave sampling equals to number of fundamental waves, the sequence of the sampling values from sampling points must be matched one by one with the sequence of the coefficients of fundamental waves. the sampling composed by sequences of the sampling values must be full sampling ; the relevant deductions of the theory of dissolvable signal shows that when sampling the signal, sampling frequency must be lager than the ratio of the number of fundamental waves to the occupation time of the fundamental waves ; to band - limited signals, when the fundamental wave is a sine signal, the results from the relevant deductions of theory of dissolvable signal is coherent to the classic sampling theory

    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。
