1关于数字信号处理的问题A continuous-time signal xa(t) is composed of a linear combination of sinusoidal signals of frequencies 250 Hz,600 Hz,1.1 kHz,2.4 kHz,and 3.8 kHz.The signal xa(t) is sampled at a 2.0-kHz rate,and the sampled sequence is passed through an ideal lowpass filter wit...
In particular, some embodiments of the present disclosure include a new type of a level-crossing sampling mechanism called a derivative level-crossing sampling (D-LCS). At a high level, D-LCS involves quantizing the derivative of an input signal when the derivative of the input signal crosses ...
To do this, we first present an instantiation of LTC networks and their approximate closed-form expressions. Extended Data Fig. 1 shows a liquid network with two neurons and five synaptic connections. The network receives an input signal I(t). Extended Data Fig. 1 further derives the DE ...
The spectral analysis of signals is currently either dominated by the speed–accuracy trade-off or ignores a signal’s often non-stationary character. Here we introduce an open-source algorithm to calculate the fast continuous wavelet transform (fCWT). The parallel environment of fCWT separates sca...
A low level initial acquisition signal consisting of a continuous wave signal portion followed by a phase-modulated signal portion is transmitted via a satellite to a receiving station. The received CW signal is converted by a voltage-co... Y Matsuo,J Namiki,Y Furuya - US 被引量: 21发表:...
A discrete-time signal can be represented as a sequence of numbers, which can be naturally discrete in time or it can be obtained from periodic sampling of a continuous-time signal. For instance, the value of the nth number x[n] in a sequence, usually called as sample, is equal to ...
In other words, it measures the effect of those unknown inputs which have maximum influence on the residual signal. Likewise, the sensitivity to faults is measured by the ℋ−index, first introduced by Hou and Patton (1996) and extended by Liu et al. (2005). It is the measurement of...
Using a 9.1 GHz microwave modulation and a timing signal carried by two continuous-wave lasers and transferred across the same 80 km urban fibre link, frequency transfer stability at the level of 5310219/day was achieved. Time synchronisation at the 50 ps precision level was also demonstrated. ...
62. The protein sequence of lactoferrin includes a nuclear localization signal that is highly conserved across mice and humans, consistent with important transcriptional activity63. Interestingly, mice lacking lactoferrin display normal early neutrophil development, although the respiratory burst is impaired ...
