The act of processing any <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjI_5wpEbGdrcN5Y29ycA" class="cyc_term">LogicSignal</a>. signal processing SignalProcessing http://en.wikipedia.org/wiki/Signal_processing dsp <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLYJ-JwpEbGdrcN5Y29ycA" class="cyc_term">DigitalSignalProcessing</a> (DSP) refers to manipulating information, such as representations of sound or images, that have been converted from analog into digital form.

Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWESd5wpEbGdrcN5Y29ycA" class="cyc_term">IntrinsicStateChangeEvent</a> is an event characterized primarily by a change in some intrinsic property of at least one main actor involved in the event. Such intrinsic changes may include changes of a thing's color, temperature, device state, or size. Events where the main change is extrinsic (such as a change in location or ownership) are not instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWESd5wpEbGdrcN5Y29ycA" class="cyc_term">IntrinsicStateChangeEvent</a>. In events which have more than one actor, the event may be an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWESd5wpEbGdrcN5Y29ycA" class="cyc_term">IntrinsicStateChangeEvent</a> for one actor but not for another. For example, in a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjwqZwpEbGdrcN5Y29ycA" class="cyc_term">FasteningSafetyBelt</a> event, the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViLD5wpEbGdrcN5Y29ycA" class="cyc_term">SafetySeatBelt</a> (the device used) goes from unconnected to connected (to itself), which is an intrinsic change; however, the agent who does the fastening does not change intrinsically, but only in his configuration to the belt, an external object. Another example: in a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViw4JwpEbGdrcN5Y29ycA" class="cyc_term">HairCuttingEvent</a>, the hair that is cut undergoes an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWESd5wpEbGdrcN5Y29ycA" class="cyc_term">IntrinsicStateChangeEvent</a> due to its role in that kind of event, but the barber undergoes no intrinsic change due to the hair cutting. Note that some events, such as an ice cube melting into a small puddle of water, could be represented either as an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWESd5wpEbGdrcN5Y29ycA" class="cyc_term">IntrinsicStateChangeEvent</a> or as a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVibApwpEbGdrcN5Y29ycA" class="cyc_term">PhysicalTransformationEvent</a>, but not (within a single micro-theory) as both. event that inherently involves a change of state IntrinsicStateChangeEvent The act of processing any <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjI_5wpEbGdrcN5Y29ycA" class="cyc_term">LogicSignal</a>. signal processing SignalProcessing The act of processing any <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjI_5wpEbGdrcN5Y29ycA" class="cyc_term">LogicSignal</a>. signal processing SignalProcessing type of temporally stuff-like thing A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> (q.v.) whose instances are all and only those collections that are temporally stuff-like. A collection <code>COL</code> is temporally stuff-like just in case every purely temporal part (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is itself an instance of <code>COL</code>, unless it is a temporal part of a temporal granule of <code>COL</code> (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a>). More precisely, for a collection <code>COL</code> to be an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> it is both a necessary and sufficient condition that for any <code>OBJ1</code> and <code>OBJ2</code> (with <code>OBJ2</code> at or above <code>COL</code>'s temporal granularity level), if <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. Consider <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. Take an arbitrary instance <code>WALK</code> of this collection (say Miss America 2000's victory walk down the runway and back); and then take an arbitrary time-slice <code>SUBWALK</code> of <code>WALK</code> that subsumes at least one instance of (the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a> for <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> (say her trip back from the end of the runway). <code>SUBWALK</code> is itself an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. So <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. See <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> for the disjoint notion of being temporally object-like. TemporalStuffType
