Digital Signal Processing (DSP) was, a few decades ago, a relatively obscure field associated with the mathematics of numerical analysis. As computers have become cheaper and faster, it is now ...

An optical discrete time-frequency domain transform technology is proposed for ultra-fast optical waveform measurements. By using the technology, single shot ultrafast optical phenomena in a long time ...

Analog circuit design is increasingly encountering mixed-signal circuits, and analog engineers need some understanding of discrete-time sampling circuits, whether they are sample-and-hold circuits or ...
