cartopol~ Reference

Signal Cartesian to Polar coordinate conversion

cartopol~

Description

Use the cartopol~ object to convert signal values representing cartesian coordinates to a signal composed of polar coordinates.

Examples

Use cartopol~ to get amplitude/phase data from the real/imaginary data pair that fftin~ outputs

Arguments

None.

signal

In left inlet: The real part of a frequency domain signal (such as that created by the fft~ or fftin~ objects) to be converted to a polar-coordinate signal pair consisting of amplitude and phase values.

In right inlet: The imaginary part of a frequency domain signal (such as that created by the fft~ or fftin~ objects) to be converted to a polar-coordinate signal pair consisting of amplitude and phase values.

Output

signal

Out left outlet: The magnitude (amplitude) of the frequency bin represented by the current input signals.

Out right outlet: The phase, expressed in radians, of the frequency bin represented by the current input signals. If only the left outlet is connected the phase computation will be bypassed, reducing the intensity of the computation.
