Signal converters are electronic tool that receive one type of signal and output another type of signal. There are several types of signal converters like Analog-to-digital converters, digital-to-analog converters, Frequency converters, Voltage converters, Frequency-to-voltage converters, Voltage-to-frequency converters. Signal converters convert signals from sensors into signals for industrial use and convert input analog signals into output analog signals.
The common features of signal converters are filtering and amplification. Integral filters permit some signal frequencies to pass as attenuating others. Integral amplifiers increase signals to the corresponding scale of the input device. Signal converters that contain multiplexers can unite a number of AC or DC inputs serially into one output. Signal isolation can be realized through optical isolation, magnetic induction, or the use of capacitors. Sometimes Signal converters comprise current-to-voltage converters, which create output signal voltages that are a role of the input current, and current loop converters that convert an analog or digital signal to a current loop output.
