Description

In modern communication systems, digital delivery methods have become prevalent. These applications provide a discrete data stream that allows for greater immunity to noise as well as reduced bandwidth. Transmission systems now have to utilize complex modulation or combining of many carriers in order to deliver this digital data stream. One problem associated with these transmission systems is they can no longer be measured accurately with a conventional diode-based power measurement. In order to fit the needs of these expanding digital applications, square-law detectors can be used to give accurate average power measurements.
