Dirac delta

The Dirac Delta or unit impulse function is defined as

Multiply a Function by an Impulse

When we multiply the unit impulse function by a function which is known to be continuous at . Since the impulse has nonzero value only at , we get . We can view the result as another impulse located at with strength .
