You'll recall that after Apple's iPhone 4 press conference, in which they showed that other phones exhibit the same signal attenuation issues as the iPhone 4 (except that instead of a finger touch, it ...

PCB design guidelines are created as benchmarks for circuit design engineers to meet the industry standards. Following these guidelines will ensure better manufacturability and robust product ...

In DC to low-frequency sensor signal-conditioning applications, relying on the common-mode rejection ratio (CMRR) of an instrumentation amplifier to provide robust noise rejection in harsh industrial ...

Transmitting high-speed data over a cable or printed-circuit-board (PCB) path will significantly attenuate and distort the signal. Transmission paths are usually transmission lines that introduce ...

The weakening of RF energy from an RFID tag or reader. The energy emitted by the reader naturally decreases with distance. The rate of decrease is proportional to the inverse square of the distance.

What does receiver sensitivity really have to do with wireless system performance? Along with transmit power and antenna gains, it is a key indicator not only of the ...
