Analog Signal Processing Samples

Analog signal processing samples for the OMRON NX/NJ series.
Sample programs for signal analysis and waveform processing on PLCs, such as analog graph display, digital filters and FFT (fast Fourier transform).

Samples

Analog graphs

Displays analog input values on the NA screen as line graphs or oscilloscope-style graphs.

Digital filters

Calculates LPF, HPF, BPF, Notch, LSF, HSF, Peak and AllPass filters

FFT

Performs frequency analysis of vibration data and analog signals using FFT (fast Fourier transform).
