Makes a complex rotator block. The phase increment (in radians) is how much phase will be added to the input every value.

Parameters

(R): Run-time adjustable

Phase Increment (R)
Acts as the rotational velocity.

Example Flowgraph

In the example below a constant source, set to 0.5, is fed into the rotator, thus producing a sine wave. The phase increment is set to 0.01 radians and the sample rate is 100kHz, so that equates to 1000 radians every second, or 1000/(2pi) = 159 cycles per second. This corresponds to a period of about 6ms, as shown in the time sink.
