cartopol~

Signal Cartesian to Polar coordinate conversion

Description

cartopol~ will take any given signal as a cartesian coordinate and output the polar conversion of that signal.

Arguments

None.

Messages

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.

Information for box attributes common to all objects

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.

Examples

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