Modulation transfer spectroscopy (MTS) has emerged as a pivotal technique in modern atomic physics and optical metrology. By utilising the nonlinear interaction between a modulated pump beam and an ...

Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Until the last few years, the narrow bandwidth (300kHz) of the 950MHz radio channels, which was adequate for the audio and technical standards of the all-analog world, was insufficient to handle the ...

In Part I of “Testing on the EDGE” in the February issue of EE, we looked at some of the basics of GPRS and EDGE technologies. Part II focuses on what is needed to test a GPRS or EDGE mobile radio.
