Digital Filter - Mitsubishi Electric MELSEC iQ-R User Manual

Digital filter

Medium speed Low speed
When data is obtained from a sensor connected with the A/D converter module, an analog input value may be output with
unnecessary noise from the sensor. This function eliminates noise by attenuating unnecessary frequency data to obtain only
digital values with target frequency data.
Select the low pass filter, high pass filter, or band pass filter depending on the sensor connected. When the high pass filter or
band pass filter is used, direct signals are eliminated.
