Synthetic biologists have added high-precision analog-to-digital signal processing to the genetic circuitry of living cells. The research, described online today in the journal Science, dramatically ...

In their piece, Tsaftaris and Katsaggelos describe these experiments while stirring the engineering community towards “a possible not-so-electronic future” of digital signal processing.

In any event, performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future.

Digital signal processing is more than just ADCs, DACs, and algorithms. Moving processing closer to the peripherals can improve performance and power usage.

In this case, it is light-wave processing. The concept of optical digital signal processing in some ways is a misnomer because optical signals are by their very nature analog. Nevertheless, there is a ...

The quadrature processing techniques employed in spectrum analysis,computer graphics, and digital communications routinely require highspeed determination of the magnitude of a complex number (vector ...

This approach requires extremely fast converters, high-bandwidth digital data links, and powerful real-time digital signal processing.

Most wireless headphones and speakers rely on some type of digital signal processing. Here's what you need to know about DSP—and why it's hard to avoid.
