WebThreshold- and signal-detection-based models have dominated theorizing about recognition memory. Building upon these theoretical frameworks, we have argued for a dual-process … WebA CFAR detection occurs when the input signal level in a cell exceeds the threshold level. The threshold level for each cell depends on the threshold factor and the noise power in that derived from training cells. To maintain a constant false alarm rate, the detection threshold will increase or decrease in proportion to the noise power in the ...

WebThe term ‘signal’ in pharmacovigilance entails considerable ambiguity. The potential for confusion about the meaning of ‘signal’ may be amplified with increased used of … WebFirst, to improve detection reliability, increased sensing time is required. Moreover, there is a minimum SNR below which no signal can be detected. Noise uncertainty, caused by various factors (e.g., temperature changes, ambient interference, and filtering), is unavoidable and leads to errors when setting the threshold for signal detection.
