threshold detector

threshold detector

[′thresh‚hōld di‚tek·tər]
(nuclear physics)
An element or isotope in which radioactivity is induced only by the capture of neutrons having energies in excess of a certain characteristic threshold value; used to determine the neutron spectrum from a nuclear explosion.

It is shown in [17-19] that the performance of a cognitive radio network can be improved by utilizing the double threshold detector for local detection.
A simple amplitude threshold detector in previous JRC system can demodulate the EBPSK modulated pulse echoes, resulting in a simple receiver structure.
A threshold detector automatically sends an interrupt to the processor if the average power level of any DDC core falls below or exceeds a programmable threshold.
This situation, which is caused by the presence of bias in the coherence estimate especially for low values [5], degrades considerably the detection performance of the sample threshold detector (see Section 5).
* An EnOcean STM 110C solar powered sensor transmitter (STM) module--the STM module integrates a wireless sensor, a low-power radio, a solar cell power generator, a microcontroller, an ultra low-power sleep timer and a threshold detector for energy management.
Receiver circuits for serial digital signals consist of an input signal conditioning, a clock recovery circuit and a threshold detector. The clock recovery circuits are designed to track low rate variations in the incoming data frequency.
Voltage threshold detector set at 0.8 volts to detect '1's
If the A/C input is set low, the operation will be dependent upon the status of the threshold detector. If the RF input signal level is below the set threshold, the device will be armed, ready to initiate a conversion (with delay) after the threshold is exceeded, at which point a single conversion will take place.
It has a threshold detector to eliminate faulty discharge counts and a touch-panel display including a keypad for parameter setting and control showing functional and test data.
To monitor the signal level in an RF path, a switch is used to divert the signal at the monitoring point to the threshold detector. Continuous monitoring of the signal level is accomplished by using a directional coupler to divert a portion of the signal to the threshold detector, allowing the remaining signal to continue along the signal processing chain, as shown in Figure 5.
A new line of coaxial threshold detectors designed for microwave and millimeter wave applications can be used for analyzing radar performance, leveling pulsed signal sources, and making AM noise measurements.
