wrap — Wraps-around the signal that exceeds the low and high thresholds.
xsig -- input signal
klow -- low threshold
khigh -- high threshold
wrap wraps-around the signal that exceeds the low and high thresholds.
This opcode is useful in several situations, such as table indexing or for clipping and modeling a-rate, i-rate or k-rate signals. wrap is also useful for wrap-around of table data when the maximum index is not a power of two (see table and tablei). Another use of wrap is in cyclical event repeating, with arbitrary cycle length.
