What Is a Signal Detector?
A signal detector is a device designed to detect and analyze electrical or optical signals.
Its primary use spans across measurement, control, and communication fields. The core principle involves detecting signal characteristics like strength and frequency to identify signal types and confirm their presence. Signal detectors come in various forms, each tailored for specific signal types and applications, consisting of both input and output components.
Signal detectors are integral in a range of applications, including the measurement and control of electrical signals, optical signal analysis, and communication systems. For instance, they are used in devices such as voltmeters and ammeters for electrical measurements, light intensity meters for optical analysis, and in programmable logic controllers (PLCs) and field-programmable gate arrays (FPGAs) for advanced control and communication functions. Given the diverse specifications required for different signal types and environmental conditions, selecting the appropriate signal detector and understanding its correct installation methods are crucial.
