WebThe poles of a transfer function generally are of three types: simple, repeated and conjugate poles. If the values are real and non-repetitive, then such poles are known as simple poles. Example: s = 0, 2, -4 etc. While when the values of the poles are repetitive then such poles are known as repeated poles. Example: s = -1, +1, -2, -2 etc. WebThe above equation represents the transfer function of a RLC circuit.
