Domain-specific¶
- Filter (Signal Processing)
- … impulse response and cannot be implemented as a finite causal FIR filter exactly; finite designs introduce a transition band and approximation ripple. A zero-phase forward–backward digital operation uses future relative to the forward pass and is appropriate offline, not as an ordinary real-time causal filter.
This sourceMaintained implementation documentation supporting forward–backward zero-phase filtering, doubled effective order, boundary handling, and second-order-section numerical caution.
