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 ...

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 ...

At the business ends of the extensive web of fibre optic cables that thread around the world, the pulses of light they carry have to be converted into electronic signals. This is done using ...

There’s an old saying: Tell me and I forget, teach me and I may remember, involve me and I learn. I’m guilty of this in a big way — I was never much on classroom learning. But if I build something or ...

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 ...
