Re: Timed signal and power of Phase component

Hi,

As I understand, when a timed signal goes through a Complex to Polar block, it will be split into a Mag and Phase component.

1. I would like to observe the peak to peak value of the phase component. What can I do so that I can observe the Phase component, like a timed signal [ts(Phase) doesn't help]?

2. How can I measure the power of the phase component?

Thanks in advance.

No one else has this question

I and Q signals which are derived from Ptolemy or CircuitEnvelope Analysis are time domain signals.
So "ts(Phase)" isn't appropriate.

Just plot Phase, then you can get time v.s. Phase plot.

Hi Tnaka,

Thanks for the reply.

I realised that if you have a Timed signal, which is "complex" in nature, you can actually pass the signal through a "Time to Float" converter, before viewing.

Hi.

You first mentioned viewing phase vs time.

Do you want to view RF waveform with carrier ? ???
If so, you should use "FcChange" with FcOut=0.

If you use "Time to Float" converter, time stamp information will be lost.

I am a little confused too.

If you want to observe the phase of a timed RF signal vs time you can use a PM_Demod component.

An alternative would be to connect the timed RF signal to

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Phase
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -> FloatToTimed -> Phase vs time
RF sig -> TimedToCx -> CxToPolar
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ->
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Mag
