Reciprocal of a signal
"Reciprocal" returns the reciprocal of the given signal:
Note that signal values close to zero create large reciprocals that will dominate the result.
Using "Reciprocal" and Product consecutively, it is possible to divide one signal by another (see example below).
A few lines from a simple macro yielding the pointwise quotient of two signals num and den as implemented in Quotient.dpm:
signal num, den, tmp, result;
tmp = Reciproc(den);
result = Product(num,tmp);
y = Reciproc(x);
