Re: Signal source block periodic phase deviation problem

[Ceren Karaköse]

Hi Engin,

The phase is constant. You're observing a constant phase sinusoid in real-time (using time sink) within a specified duration (which is determined by the number of points parameter of time sink). The time sink graph gets updated in real-time, hence the jitters seem to be happening.

Best,

Subject: Signal source block periodic phase deviation problem

 

Hi everyone,

I am running a simple flowgraph where signal source block generates sine
wave and time sink shows waveform. Sample rate is 100 Msps and carrier
frequency is 1 MHz.


But phase of signal deviates periodically, you can see from link given
below.

Is there any way to circumvent this? Like changing a variable from inside
a block?
