Optoelectronic coupling DC control circuit and its application

1 Overview Optocoupler is also called optoisolator, optocoupler or optocoupler. It is a device that uses light as the medium to transmit electrical signals. Usually, the light emitting device (infrared light emitting diode LED) and the light receiver (photosensitive semiconductor tube) are packaged in the same shell. When an electric signal is applied at the […]

Application of LabVIEW FPGA module in clock circuit

To execute code using the data flow model, LabVIEW synchronizes the logic on the FPGA. By default, LabVIEW FPGA places a register between logic functions in the program block diagram to maximize the propagation time required for each operation. Propagation delay is the time required for a signal to propagate from one register to the […]
