If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

In nature, most of the signals we measure (sound, light, etc.) are defined over continuous domains (time, space, etc.). In order to process them with computers, we need to transform the continuous ...

Aliasing is thankfully becoming a less frequent problem due to improved instrument designs. Users should still be aware of it to prevent time- and money-costly errors. Aliasing is an ever-present ...

In order to store this continuous image on a computer, we need to sample it and convert it into a discrete image, $\ell [ n,m ]$. @fig-aliasing (b) shows the resulting sampled image when the sampling ...

Abstract: The problem of sampling continuous-time spectrally correlated (SC) processes is addressed. SC processes have Loève bifrequency spectrum with spectral masses concentrated on a countable set ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Abstract: A microgrid usually contains a large amount of power electronic inverters, the interaction of these inverters can introduce a series of system instability and power quality issues. Inverter ...
