The present disclosure shows new mechanisms fir sampling an input signal. 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 ...
Most signals present in our daily life are continuous in time such as music and speech. A signal is a function of an independent variable, usually an observation measured from the real world such as position, depth, temperature, pressure, or time. Continuous-time signals have a continuous inde...

Thus, a discrete-time signal x[n] and the corresponding continuous-time signal x(t) are related by a sampling process: (0.1)x[n]=x(nTs)=x(t)|t=nTs. That is, the signal x[n] is obtained by sampling x(t) at times t=nTs, where n is an integer and Ts is the sampling period...
When comparing continuous time models computed from sampled data, it is important to consider the intersample behavior of the input signal. In the example so far, the input to the system was piece-wise constant, due to the Zero-order-Hold (zoh) circuit in the controller. Now remove this ...
This example shows how the variable time-frequency resolution of the continuous wavelet transform can help you obtain a sharp time-frequency representation. The continuous wavelet transform (CWT) is a time-frequency transform, which is ideal for analyzing nonstationary signals. A signal being non...
This spectrum plot is a frequency-domain representation that tells us at a glance "how much of each frequency is present in the signal." In Chapter 4, we extended the spectrum concept from continuous-time signals x(t) to discrete-time signals x[n] obtained by sampling x(t). In the ...
For each value of , the time-domain signal , for , is the output of the th ``filter bank channel,'' for . In this ``filter bank'' interpretation, the hop size can be interpreted as the downsampling factor applied to each bin-filter output, and the analysis window is seen as the ...
Light serves as the energy source for plants as well as a signal for growth and development during their whole life cycle. Seedling de-etiolation is the most dramatic manifestation of light-regulated plant development processes, as massive reprogramming of the plant transcriptome occurs at this time...
More particularly, the signal processing apparatus of the present invention employs pipe-line architecture for analyzing in delayed real time the frequency spectrum of an information component (having one or more dimensions) of a given temporal signal having a highest frequency of interest no greater ...
