Digital Resonator
Table of Contents
A unique two-pole bandpass filter called a digital resonator has two complex conjugate poles that are close to the unit circle. The term “resonator” describes a filter that responds more strongly in magnitude near pole locations. Many uses for digital resonators exist, such as speech generation and basic bandpass filtering.
Digital Resonator
- It is a two-pole bandpass filter with complex conjugate poles that are situated close to the unit circle.
- Near the poles, the frequency magnitude response resonates. It is receiving a strong response.
- The angular position of the poles affects the filter’s resonance frequency.
- We can select two zeros & two poles system to represent DR
- Select two zeros at the origin.
- Select one zero sat +1 and -1
