Lessons from the RF Analyzer
The proper instrument can allow the unseen to become observable. Dale uses his HP RF analyzer to demonstrate some wireless mic issues that audio people must deal with everyday.
Impulse vs. Sine Sweep Response
What's the best way to get room data? Some advocate impulsing the room with balloons or starter's pistols. Others prefer using swept sine waves. Don sheds some light on this old argument with some reminders about each method's susceptibility to amplitude non-linearities.
The Electrostatic Field and Electrostatic Potential Relationship
This is the fourth of a series of articles describing the properties of coaxial cable.
The Conduit Transformer
This paper intends to show how a simple error in power
wiring geometry inside the conduit can create a transformer
which induces voltage on the ground wire. This can ruin an
otherwise well designed technical power and ground system.
