wave sample meaning in English
波取样器
Examples
- Design of hardware consists of three pll loops , micro wave sample mixer , fractional - n frequency divider
硬件电路包括三个锁相环,取样混频器,分数分频器的设计等。 - For hardware , the sensor and wave sampling system are improved . for software , according to the impact of white noise , an algorithm of denoising based on wavelet transform is presented
硬件方面改进了传感器和波形采集电路；软件方面针对白噪声对监测结果的影响提出了基于小波变换的除噪滤波算法。 - 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
本文通过分析认为，当信号集中的任一信号可表示为一系列已知信号的线性代数和时，信号集便构成可分解信号集，已知信号称为基波信号；对可分解信号而言，基波系数构成一序列，当对指定的基波信号集分解唯一确定时，系数序列本身便是信号的一个表示；可分解信号采样定理指出当基波样值矩阵的秩等于基波数时，则由采样点处的采样样构成的样值序列必与基波系数序列一一对应，从而由该样值序列构成的采样必为完全采样；可分解信号采样定理中的推论指出，对信号集进行采样，采样频率必须大于其信号分解的基波数与其对应时长之比；对有限带宽信号，若基波信号为正弦信号时，由可分解信号采样定理推论给出的结论与经典采样定理一致。
