FIR Characteristics

• Output Is Determined Solely From Previous Inputs

Y = C0X0 + C1X1 + C2X2 + ….

CN = Coefficients

XN = Delayed Data

• Result is an Inherently Stable Filter

  • Filter Will Never Go Unstable and Oscillate

• Constant Delay Through the System

• More Computation Intensive Than if Output is Based on Previous Output (Recursive or IIR Filter)
