■MOVING AVERAGE OUTPUT (model: JFTS1)

The JFTS1 samples input signals every H seconds and

outputs proportionally to an average of N numbers of

sampled data. When a new input is sampled after

another H seconds, it gives up the oldest sample and

calculates a new average including the latest sample

and outputs proportionally.

■ DEAD-TIME COMPUTING (model: JFTS2)

The JFTS2 does not respond to an input signal for a

preset dead-time duration. In addition, with adjusting

a time constant T, it generates a first order lag output

after the dead-time.

Dead Time = H × N (s) (H ≤ T)
