atonek

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.
