Wireless is everywhere, but not without spectral measurements.
If you work on RF/microwave circuits or digital wireless systems, you surely make measurements in the frequency domain. In 2014, Scitech Publishing released the second edition of Spectrum and Network Measurements by Robert A Witte. Originally published in 2001, this classic needed an overhaul because of the rapid changes in wireless communications. (Read Kenneth Wyatt's book review on EDN>). This week's quiz questions come from the second edition.
