Practical Tips On Measuring Interference
By Anritsu Company
By utilizing the ISM (industrial-scientific-medical) frequency bands, the wireless industry has been able to exploit the increasing popularity of unlicensed communication systems. However, their unlicensed nature carries with it the seeds of serious signal interference problems. Such ISM system designs are type-approved but are then installed by unlicensed owners or contractors. These conditions sometimes lead to signal configurations that unintentionally interfere. The objective of this article is to present measurement tips and procedures that will help a field technician measure signal interference in operating communications systems.

Analog Circuit Design Series (Four-Volume Set)
By D. Feucht


This four-volume set of books reduces the concepts of analog electronics to their simplest, most obvious form that can easily be applied (even quantitatively) with minimal effort. The emphasis of the set is to teach through inspection how circuits work and how to apply the same techniques to circuits of the same class.
