This paper gives a survey of sub-Nyquist sampling. Sub-Nyquist sampking is of great interest in the environment that sampling by Nyquist rate is infeasible due to either hardware or software limitation. The survey summarizes a number of recent important researches on sub-Nyquist sampling (compressive sensing). In addition to the basics of sub-Nyquist sampleing, including the fundamental theory ...

Nyquist is a programming language for sound synthesis and music composition. Nyquist has evolved from a text-only programming language to include an integrated development environment (IDE) that adds graphical support for many tasks. Nyquist is also hosted by Audacity, a widely used audio editor that can invoke Nyquist functions written in the form of scripted plug-ins. This article shows by ex...

In conventional hard disk drives, a control system compensates for vibration in which the frequency is higher than the Nyquist frequency by using a multi-rate filter that decreases the gain above the Nyquist frequency. However, such a control system can only avoid instability and cannot suppress disturbances above the Nyquist frequency. In response to this problem, a control system design metho...

This letter studies the consensus tracking control for multi-agent systems (MASs) of general linear dynamics considering heterogeneous constant known input and communication delays under a directed graph containing spanning tree. First, open-loop stable MASs, distributed predictive observer is proposed to estimate error construct that does not involve any integral term (which time-efficient in ...

The terahertz electromagnetic band has been foreseen as a promising candidate to accommodate the ever-increasing wireless data traffic. To this end, development of novel transceiver architectures and signal processing solutions is crucial handling massive volume transmitted over communications networks. In paper, we propose waveform that shows full compliance with spectral emission mask imposed...

It is shown that the Hopf bifurcation occurs as the bifurcation parameter, the mean delay, passes a critical v...

A humongous development in the study of Nyquist filter has been observed in the recent years. This paper presents a review of the work done on a Nyquist filter in the last decade. Nyquist filter is called M th band filter because it has zero coeffient at every M th sample except its middle coefficient. Different filter methods have been proposed with the focus of improving filter parameters lik...

It is often claimed that classical control was a product almost entirely of the wartime laboratories of the United States and, to a lesser extent, the United Kingdom. World War II, however, was not quite such a watershed as is often claimed. Even before the war, in a number of countries, process control was moving toward an understanding of three-term (proportional-integral-derivative) control....

We introduce a full hardware implementation and demo of a sub-Nyquist radar receiver. Our system demonstrates pulse-Doppler radar transmission and reception at sub-Nyquist rates. Specifically, we sample the received radar signal at 1/20 the Nyquist rate, while still perfectly detecting the targets in the delayDoppler plane. In addition our system filters clutter interference from the sub-Nyquis...
