Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies around the sampling frequency, fS. When the difference signals fall into the ...

An electro–optic scheme for sampling the electric field of laser pulses without the need for any synchronization could become a valuable tool for characterizing sources that emit in the infrared and ...

This example illustrates the use of regression analysis in a simple random cluster sampling design. The data are from S rndal, Swenson, and Wretman (1992, p. 652). A total of 284 Swedish ...

Abstract: As electromagnetic environments become increasingly complex, the demand for ultra-wideband signal reception has become more widespread. Traditional Nyquist sampling theorem requires high ...

Abstract: Power spectrum sensing has been a task with longstanding interest in the concept of cognitive radio, where knowing the power distribution over frequencies suffices applications like resource ...

How to evaluate a DAC’s analog output. How to avoid effects such as standing waves from disturbing measurements. How to adapt the fundamental frequency-response measurement method for use when digital ...
