Mike: Nearly every analog instrument uses the 4-20 mA loop. Field transmitters, positioners, and variable frequency drives ...

It used only one synchronous signal to control two sets of switches. Experimental results showed that the short current could be limited within 100 A. The proposed driving circuit was applied to a ...

This paper proposes a frequency-adjustable signal generator based on Xilinx FPGA and uses Verilog language to realize long-range waveform output and adjustment through UART serial communication ...
