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.

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.
If the A/C input is set low, the operation will be dependent upon the status of the threshold detector.
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.
