limit — Sets the lower and upper limits of the value it processes.
xsig -- input signal
klow -- low threshold
khigh -- high threshold
limit sets the lower and upper limits on the xsig value it processes. If xhigh is lower than xlow, then the output will be the average of the two - it will not be affected by xsig.
This opcode is useful in several situations, such as table indexing or for clipping and modeling a-rate, i-rate or k-rate signals.
