The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3] [9] which is the amount of additional signal loss applied by the echo canceller. Most echo cancellers are able to apply 18 to 35 dB ERLE. The total signal loss of the echo (ACOM) is the sum of the ERL and ERLE. [9] [10]
Latency depends on packet time, propagation and queuing delays, packet processing overhead, and buffering in the destination device; thus minimum latency is the shortest packet time and network forwarding time, which can be less than 1 μs on a point-to-point Gigabit Ethernet link with minimum packet size, but in real-world networks could be ...
Adaptive feedback cancellation originated during the evolution of the hearing aid. The hearing aid became digital, and as such feedback cancellation was needed. In 1980 a directional microphone was introduced in the digital hearing aid, and adaptive feedback cancellation was created to block external noise that the microphone picked up. Today ...
Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound in the transmission medium.

The recording of a heart beat (an ECG), may be corrupted by noise from the AC mains.The exact frequency of the power and its harmonics may vary from moment to moment.. One way to remove the noise is to filter the signal with a notch filter at the mains frequency and its vicinity, but this could excessively degrade the quality of the ECG since the heart beat would also likely have frequency ...
Andrey Demskiy, 28, is accused of first attacking his wife and mother-in-law before beheading his 1-year-old son with a knife, the Sacramento County Sheriff’s Office said.
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
