Digital filter design underpins modern signal processing by enabling precise shaping of signal spectra for a wide range of applications including telecommunications, audio engineering, biomedical ...

Variable fractional delay (VFD) filters are digital filters capable of introducing precise, continuously adjustable delays that are non-integer multiples of the sampling period. Such filters play a ...

A unique filtering technology that combines light and sound waves on a single chip is expected to better detect radar and communications frequencies. "We have developed a powerful signal filtering ...

Analog signal processing has conventionally been viewed as a voltage-dominated form of design. But voltage-mode processing can restrict the system's dynamic range. There is also a limitation on the ...

CATALOG DESCRIPTION: discrete-time random process, second-order statistics, autoregressive and moving average processes, linear prediction, Wiener filter, stochastic gradient (Least Mean Square) ...

Small or embedded systems often require a delicate measurement in the presence of high noise or interference. Without fancy filtering hardware, high-speed processing, or digital signal processing, it ...

Pulse oximeters, a type of photoplethysmography (PPG) sensor, are electronic devices that measure a person’s blood-oxygen saturation (SpO 2) and heart-rate (HR) levels. Since their inception in the ...
