Limiting: Any process by which a specified characteristic (usually amplitude) of the output of a device is prevented from exceeding a predetermined value. Output is the term denoting either an exit or changes which exit a System and which activate/modify a Process.
Limiting can refer to non-linear clipping, in which a signal is passed through normally but "sheared off" when it would normally exceed a certain threshold. It can also refer to a type of variable-gain audio level compression, in which the gain of an amplifier is changed very quickly to prevent the signal from going over a certain amplitude. Dynamic range compression, also called DRC (often seen in DVD player settings or simply compression, is a process that reduces the Dynamic range of
- Hard limiting ("clipping") is a limiting action in which there is
- (a) over the permitted dynamic range, negligible variation in the expected characteristic of the output signal, and
- (b) a steady-state signal, at the maximum permitted level, for the duration of each period when the output would otherwise be required to exceed the permitted dynamic range in order to correspond to the transfer function of the device. Clipping is a form of Distortion that limits a signal once it exceeds a threshold Dynamic range is a term used frequently in numerous fields to describe the Ratio between the smallest and largest possible values of a changeable quantity such as in Sound In Telecommunication, signalling (UK spelling or signaling (US spelling has the following meanings The use of signals for controlling communications A transfer function is a mathematical representation in terms of spatial or temporal frequency of the relation between the input and output of a ( linear time-invariant)
- Soft limiting is limiting in which the transfer function of a device is a function of its instantaneous or integrated output level. The output waveform is therefore distorted, but not clipped. waveformogg|right|a sine square and sawtooth wave at 440 hz]] Waveform means the shape and form of a signal such as a Wave moving in a solid liquid or gaseous
