Fig. 29: Oversampling 20 ksps with 2 x EL3751 with input signals (below) and result signal (top)
The upper diagram shows the total signal and the two input signals (nSample_1, nSample_2), with a time
shift of 50 µs relative to each other, within 18 s in compressed form. The total input signal (nCollectedResult)
indicates the interlacing of the two input signals.
The following diagram (enhanced through highlighting) shows how the input signals (nSample_1,
nSample_2) contribute to the structure of the total input signal:
Fig. 30: Oversampling 20 ksps with 2 x EL3751 shows input value 1 and input value 2 alternately for a result
value
Under certain conditions, both inputs can be combined into a single variable in a correspondingly fast task.
For this purpose the sample program contains an additional task with 50 µs cycle time, which is required for
representing the input signals in the SopeView and contains a variable (nCollected) to which both inputs are
assigned alternately:
// 50 µs task
