Glottal inverse filtering (GIF) is a pivotal signal processing technique that permits the extraction of the glottal flow waveform by effectively cancelling the influence of the vocal tract and lip ...

Wavelets provide new capabilities for analyzing real-time signals. This introductory article provides an overview and presents the basic mechanisms involved in wavelets. In many signal processing ...

Optical signal transmission can be significantly improved by limiting the wavelength of transmitted signals. Fiber Bragg grating (FBG) is a technique widely used in optical communication, sensing, and ...

A data filter is a device, algorithm, or process that removes some unwanted components or features from a data signal. The unwanted component may be random noise (perhaps from mixing turbulence or ...

Driving an analog-to-digital converter (ADC) for optimum mixed-signal performance is a design challenge. Figure 1 shows a standard ADC driver circuit. During ADC acquisition time, the sampling ...

As every engineer learns at an early stage, clock edges must be obeyed. In the digital domain, synchronization through global and local clock trees, slew rate and rising/falling times all combine to ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...
