Document Summary
A signal is a function of one or more independent variables. tv voltage i t current. Signals (cid:149) often (e. g. this course) time is the independent variable (cid:149) continuous time, t is a real number: v(t) (cid:149) discrete time, n is an integer: v[n] v(t) v[n] 2 -1 0 1 2 3 4 5 t. 2 -1 0 1 2 3 4 5 n. If e is finite then p must be 0. If p is >0 then e is infinite. If p is infinite then e is infinite. In radians is dimensionless y d x (length / length) x = r cos y = r sin . R is the magnitude | z | Is the angle z z = x + j y = r cos j r sin . = r (x, y) + (u, v) = (x+u, y+v) r q r q ( + ) Review of sinusoids j ( t imaginary axis y.
