NAME

noise - filter valuator motion

SYNOPSIS

C
noise(v, delta)
Device v;
short delta;

FORTRAN
subroutine noise(v, delta)
integer*2 v, delta

Pascal
procedure noise(v: Device; delta: Short);

DESCRIPTION

Noise determines how often queued valuators will make entries in the event queue.  Some valuators are "noisy": an unmoving device may report small fluctuations in value.  The noise command allows the user to set a lower limit on what constitutes a move.  That is, the value of a noisy valuator v must change by at least delta before the motion is considered significant. For example, noise(v,5) means that valuator v must move at least 5 units before a new queue entry is made.

NOTE

This command can only be used in immediate mode.
