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 ...

Frequency modulation spectroscopy is a nondestructive technology for determining the water activity of pharmaceutical samples. This article discusses the various pharmaceutical applications of ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

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 ...

The most effective weapon in the infrastructure system designer's arsenal is the use of Direct Conversion Receiver (DCR) and Direct Conversion Transmitter (DCT) architectures for the BTS portion of ...
