WebMar 16, 2024 · The phase step then seems to simply be 1/q. For example: In case q = 1, the phase increment will be 360° (or 0°). In case the ratio will be for example 1.3333 (4/3), i will need to make a 2Pi/q = 270° step each time. In case the ratio will be (taken from your example) 7/6, the step phase increment size is 2Pi/q = about 308.6°.
