UNIT STEP&IMPULSE FUNCTION

UNIT STEP FUNCTION


The Heaviside Unit Step Function defines functions encountering ideal On/Off

The Heaviside unit step function turns on a function at t0


The switch (change) at t0 is in fact an impulse, i.e., the Dirac delta function.



DIRAC DELTA OR UNIT IMPULSE FUNCTION



The Dirac delta function works like a sampling gate at t0,


The effect of the sampling gate accumulated through the domain t is the unit step function.
