Any process by which a specified characteristic (usually amplitude) of the output of a device is prevented from exceeding a predetermined value (188) Note 1: 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 Note 2: 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
Where an audio signal is not allowed to have excursions beyond a certain point, either positive or negative This can be done either deliberately, as with a limiter, or accidentally where the signal is clipped and therefore distorts
strictly limiting the reference of a modified word or phrase; "the restrictive clause in `Each made a list of the books that had influenced him' limits the books on the list to only those particular ones defined by the clause
A search strategy that narrows a search, resulting in a smaller set of search results
A term to describe that an amplifier has reached its point of saturation or maximum output voltage swing Deliberate limiting of the signal is used in FM demodulation so that AM will not also be demodulated
