What is a pole in signal processing?
Also, the system function for systems described by difference equations is a ratio of polynomials. The roots of the denominator and numerator polynomials are called the poles and zeros of the system. The system function is a powerful tool for the signal-processing practitioner.
What is pole zero gain?
Zero-pole-gain models are a representation of transfer functions in factorized form. For example, consider the following continuous-time SISO transfer function: G ( s ) = s 2 − 3 s − 4 s 2 + 5 s + 6. G(s) can be factorized into the zero-pole-gain form as: G ( s ) = ( s + 1 ) ( s − 4 ) ( s + 2 ) ( s + 3 ) .
