Constellation Modulator delay calculation

Hi everybody, I just want to know how the delay of the "Constellation Modulator" block in GRC is calculated. In fact, whether you set the block's last parameter "truncate filter transient" or not, a delay of 86 samples could be generated, no matter how many points are in the constellation. This m

So TX has a priority over RX, am I right? On Tue, Jan 10, 2023, 21:54 Daniel Estévez wrote: > On 09/01/2023 18:20, Karen young wrote: > > Hi, > > > > I want to use the single port (TX/RX) from USRP B210 to switch between > > transmitting and receiving. I have selected "Ch0: Antenna: TX/RX" for

Re: USRP B210 TX/RX switching between transmitting and receiving

Okay, we thought that when a TX signal sent, RX will be interrupted. That was what I meant. On Tue, Jan 10, 2023, 22:32 Marcus D. Leech wrote: > On 10/01/2023 14:01, okan erturk wrote: > > So TX has a priority over RX, am I right? > > Not sure what you mean by "priority". > > The RX/TX port will

Re: Constellation Modulator delay calculation

Hi Ali - your flowchart has no device and no throttle. You need to add a throttle. And I don't the expertise or the time to look at the source code. So I'm punting back to the list. -- Cinaed On 1/10/23 03:10, Ali G. Dezfuli wrote: Hi everybody,expertise I just want to know how the delay o

Re: Constellation Modulator delay calculation

Ali, I think the example uses the generic_mod block inside. This block uses the polyphase arb resampler for antialiasing. The line that computes the rrc delay is here
