An approximation to coherent sampling, also known as boot-strapped waveform averaging, is presented. The method uses digital cavities to determine the condition for coherent sampling. It can be used to increase the effective sampling rate of a repeti

Generalized lock-in amplifiers use digital cavities with Q-factors as high as 5X10^8. In this letter, we show that generalized lock-in amplifiers can be used to analyze microwave (giga-hertz) signals with a precision of few tens of hertz. We propose

We herein formulate the concept of a generalized lock-in amplifier for the precision measurement of high frequency signals based on digital cavities. Accurate measurement of signals higher than 200 MHz using the generalized lock-in is demonstrated. T

Sociala media genererar stora mängder data men det finns fler saker som gör det och lagrar i NoSQL databassystem och smarta sensorer som registrerar elektrisk förbrukning är en av de. MongoDB är ett NoSQL databassystem som lagrar sin data i data

Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonline
