This Design Brief introduces a computationally efficient network that computes the derivative of a discrete time-domain (digital) sequence. While recursive differentiating networks exist, this ...

Click on image to enlarge. Click on image to enlarge. Differencing, which is the discrete time analog of differentiating, removes low-frequency power in the signal, making it a bounded signal that ...

Frequency domain representation of discrete-time signals and systems. The Discrete-time Fourier transform. The z-transform, the inverse z-Transform, z-Transform properties. Sampling of continuous-time ...

Signal processing in the digital domain requires simple logic gates, which in turn creates noise-immune designs. The tradeoff for increased resolution is a greater amount of logic, though.

All earthly and celestial things emit signals. The science of signal processing, born in the 19th Century and now greatly advanced thanks to computers, allows us to better understand them.

Addressing a major roadblock in next-generation photonic computing and signal processing systems, researchers at the Harvard ...
