In addition, dynamic radio frequency interference is expected to occur in the scenarios related to cognitive radio, where the networks and the devices should exhibit frequency-agile operation.
Although many common devices exhibit the effect, they are not designed for that purpose so the effect can vary widely between one batch of a certain device and another.
Typical devices exhibit open-loop DC gain ranging from 100,000 to over 1 million.
A device characterized by steep subthreshold slope exhibits a faster transition between off (low current) and on (high current) states.
Many photographic devices use a form of strip photography due to the use of a rolling shutter for engineering reasons, and exhibit similar effects.
Resistance is the real part of impedance; a device with a purely resistive impedance exhibits no phase shift between the voltage and current.
He had seen the device exhibited at the Philadelphia Exposition of 1876 and secured Central New York rights from the Bell system.
They believed that the energy was stored in the carbon pores and the device exhibited "exceptionally high capacitance", although the mechanism was unknown at that time.
Although no passive negative resistors exist, some active devices exhibit a negative resistance characteristic.
Some devices designed in the 1960s had a negligible memory effect, but exhibited unacceptably high signal distortions at high current levels.
