6 - 2 Signals A function, e.g. sin( t ) in continuous-time or sin(2 π n / 10) in discrete-time, useful in analysis A sequence of numbers, e.g. {1,2,3,2,1} which is a sampled triangle function, useful in simulation A collection of properties, e.g. even, causal, and stable, useful in reasoning about behavior A piecewise representation, e.g. A functional, e.g. δ ( t ) ( 29 < = = 0 for 0 0 for 2 1 0 for 1 t t t t u = otherwise 0 0 for 1 ] [ n n u
