LabVIEW Data Types • Color coding of terminals and block diagram wires Integer String Boolean Dynamic Floating-point numbers The dynamic data type is a special type for use with Express VIs. However the content of the file that is generated only contains a single data point instead of the entire waveform. The dynamic data type has the actual data, a time/date stamp, and also the name of the data stream. More importantly, the dynamic data automatically converted to match the indictor value to be wired, or Express Vis, which will slow down the LabVIEW block diagram execution speed. Combine the two dynamic data, the spectrum of the original signal and the spectrum of the filtered signal using signal manipulation VI (Express->Signal Manipulate->merge signals) and connect it to the “Write LabVIEW Measurement Data” express VI (Express->Output->write meas data).
