Clock signal characterization for signal integrity
2017 IEEE 7th Annual Computing and Communication Workshop and Conference (CCWC), 2017Signal integrity analysis is usually performed solely in the time domain. The traditional way to include the frequency-dependent elements, like interconnects, is to convolve their impulse response with the input and the other circuit element models to obtain the overall response.

Gab signals for railway signaling
Journal of the A.I.E.E., 1927There is described in this paper a system of continuous signals operating within the cab of a railway locomotive. This system was developed in an effort to provide more reliable and safer signals than the common semaphore or light signals. The particular type of system is called the three-speed, continuous-control signal system.

To signal or not to signal: That should not be the question
Accident Analysis & Prevention, 2013The purpose of the present research was to examine rates of turn signal use, a positive and potentially valuable means by which drivers can communicate. A second purpose was to explore factors that might impact these rates, including the modeling influence of other drivers.

Signaling games and music as a credible signal
Behavioral and Brain Sciences, 2021Abstract The argument by Mehr et al. that music emerged and evolved culturally as a credible signal is convincing, but it lacks one essential ingredient: a model of signaling behavior that supports the main hypothesis theoretically and empirically.

Signals and Signal Transduction
2018This chapter begins by providing a brief overview of the types of external cues that direct plant growth. In general, an environmental input that initiates one or more plant responses is referred to as a signal, and the physical component that biochemically responds to that signal is designated a receptor.

IRE Transactions on Circuit Theory, 1959
As the communication art becomes more sophisticated, engineers are being called on to deal more and more with complicated signals. This trend is typified by the use of noise-like signals to combat multipath (as in the RAKE), various suggestions for improving the range and velocity resolution of radars, and the desire to evolve ways of reducing the ...

Signal abstractions in signal processing software
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1989The authors propose and formally define the concept of multilevel signal abstractions as an organizational principle for real-world signal processing software that requires both algorithmic and heuristic techniques. As an example, they have implemented a set of signal abstractions, the extended spectrum, for harmonic spectra.

Hydraulic signals in long-distance signaling
Current Opinion in Plant Biology, 2013Higher plants are sessile organisms that continuously adapt their metabolism and development in response to a changing environment. Control of water uptake and the maintenance of water status are key for the survival and optimal growth of plants. Environmental factors such as radiation, air temperature, rainfall, and humidity have a high impact on ...

It is very important that methods be developed to extract signals from the noisy backgrounds that usually accompany them. Signal processing has, therefore, become an important field in communications and in acoustics. The human ear processes the information it receives and does a reasonably good job of filtering.

An in-circuit signal analyzer for mixed signal digital signal processor
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991The architecture and functionality of a DSP hardware developmental tool called the in-circuit signal analyzer (ICSA) are discussed. This instrument is intended for embedded single chip DSP applications. ICSA is the first tool that allows for target DSP software debug integrated with signal domain analysis.
