# HT_PHASOR: Ehlers Hilbert Transform Phasor Components
| Property | Value |
| ---------------- | -------------------------------- |
| **Category** | Cycle |
| **Inputs** | Source (close) |
| **Parameters** | None |
| **Outputs** | Single series (HT_PHASOR) |
| **Output range** | Varies (see docs) |
| **Warmup** | `LOOKBACK` bars |
### TL;DR
- HT_PHASOR decomposes the price signal into two orthogonal components, InPhase ($I$) and Quadrature ($Q$), using the Hilbert Transform.
- No configurable parameters; computation is stateless per bar.
- Output range: Varies (see docs).
- Requires `LOOKBACK` bars of warmup before first valid output (IsHot = true).
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
HT_PHASOR decomposes the price signal into two orthogonal components, InPhase ($I$) and Quadrature ($Q$), using the Hilbert Transform. Together these form a complex phasor $Z = I + jQ$ that describes the instantaneous amplitude and phase of the dominant market cycle. Compatible with TA-Lib's `HT_PHASOR` function, this dual-output indicator provides the fundamental building blocks for cycle analysis, phasor crossover timing, and instantaneous amplitude measurement.
