The phrase "automatic signal" is correct and usable in written English.
It can be used in contexts related to technology, communication, or systems that operate without manual intervention.
Example: "The automatic signal from the traffic light changed to green, allowing cars to proceed."
Alternatives: "automated signal" or "self-operating signal".
This paper introduces a new bioprocess state classification methodology combining expert knowledge and automatic signal analysis, suitable for on-line application.
To warn the public of the approach of trains, the defendant railroad had installed at the crossing an automatic signal device consisting of a swinging red light and a bell.
Such changes in the underlying statistical properties of the signal and the effects of external noise often affect the performance and applicability of automatic signal processing methods that require stationarity.
Each of the schemes employs a fault detection and diagnosis system to provide accurate and timely diagnosis information to be used in an appropriate automatic signal correction algorithm for accommodation of faults in the wind farm.

DNA samples are subjected to digestion by a methylation-sensitive restriction endonuclease followed by multiplex amplification of specific genomic targets with fluorescent-labeled primers, capillary electrophoresis of amplification products, and automatic signal analysis by dedicated software, yielding the source tissue of the sample.
Automatic signalling is being introduced on the Northern line so that more trains can run more frequently.
We analyze anomalies of automatic signaling and train control equipment which occurred in 2004 on the East-Siberian Railway (corrected geomagnetic latitude ϕm = 46 51°N and longitude λm = 168 187°E).
He offers a new account of the evolution of disgust that builds on the model and argues that expressions of disgust are part of a sophisticated but largely automatic signaling system that humans use to transmit information about what to avoid in the local environment.
More modern trains, making up the majority of stock, drive and stop themselves, relying on automatic signalling.
In the UK, sensors hidden beneath roads such as Midas (Motorway Incident Detection and Automatic Signalling) allow traffic control rooms to monitor how congested a motorway has become.
