What MDA V7 Migrated formula in MDA V8 Comment
DeltaT DeltaT (time, signal) Delta (master()) + 0*Raw
(signal)
0*signal is required for applying the raster
settings based on an input signal.
Time range between the current and the pre-
vious measured value.
Calculates time(k) - time(k-1).
V8.6 assumes the first value as NoValue.
Gradient Gradient (time, signal,
count)
(signal - State_Delay (signal, NoValue
(0), count)) / (Master() - State_Delay
(Master(), 0, count))
First derivative of the last count samples.
Time range defined by sample parameter
count.
Signals of the type enumeration (VTAB) are
not supported.
Integral Integral (time, signal) Accumulate_Prefix_Integral
(signal)
Integral of signal since measure start.
LevelReached
Count
LevelReachedCount
(signal,level)
Accumulate_Prefix_Sum ((State_
Register (signal != level, !0) && (signal =
level)) ? 1 : 0)
Counts how many times a signal value has
been reached.
Time range: From start
LowPassFilter_
ASCET_lib
LowPassFilter (time,
signal, filterTime,
startInput)
Filter_LowPass1 (signal, 1 / (2*PI*-
filterTime))
Time range: From start
Maximum Maximum (signal) Accumulate_Prefix_Maximum
(signal)
Maximum value of signal since measure start.
