atonek —
A hi-pass filter whose transfer functions are the complements of the *tonek* opcode.

## Description

A hi-pass filter whose transfer functions are the complements of the *tonek* opcode.

## Syntax

kres **atonek** ksig, khp [, iskip]

## Initialization

*iskip* (optional, default=0) -- initial disposition of internal data space. Since filtering incorporates a feedback loop of previous output, the initial status of the storage space used is significant. A zero value will clear the space; a non-zero value will allow previous information to remain. The default value is 0.

## Performance

*kres* -- the output signal at control-rate.

*ksig* -- the input signal at control-rate.

*khp* -- the response curve's half-power point, in Hertz. Half power is defined as peak power / root 2.

*atonek* is a filter whose transfer functions is the complement of *tonek*. *atonek* is thus a form of high-pass filter whose transfer functions represent the “filtered out” aspects of their complements. However, power scaling is not normalized in *atonek* but remains the true complement of the corresponding unit.
