### Purpose

Reciprocal of a signal

### Description

"Reciprocal" returns the reciprocal of the given signal:

Note that signal values close to zero create large reciprocals that will dominate the result.

### Tips

Using "Reciprocal" and Product consecutively, it is possible to divide one signal by another (see example below).

### Example

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);

### Macro Synopsis

`y = Reciproc(x);`

signal x,y;
