I've been through many GRC companion tutorials, which show how to get
various sources up and running, but what if I want to have an input source
that has a straight line or parabola where the value varies based on a time
from a 0 to 5 count?
Using existing blocks can I easily implement a formula

I'm using GRC v 3.6.0 and looking at what can be done with the standard
library.
Although I've been able to apply FM to a wave, I'm still having issues
understanding how to manipulate the variables.
There is a Frequency Modulation block.. but i'm a bit confused about what

You can put a block in sequence with the samples that does two things in the
work() function:
1) copy the input buffer to the output buffer using memcpy or something
similar since it doesn't look like you need to process the samples at all
2) keep track of "number of samples remainin

Hello,
I am going to be making a C++ block which will either change the value of a
variable (which would be passed to it by a pointer) or call the tune
function of a USRP sink (passed by a pointer) after a certain number of
samples have been passed to the block. This is related to my question here.
Interesting it is, FMC (vita-57) based RF [400MHz - 4GHz] RF card [with
best ADC/DAC] and support bandwidth upto 125MHz, i feel this is a
remarkable shift in SDR manufacturing. This card fits on all of Xilinx and
ADI boards.

Hello,
I want to stream data from an external sampler to Gnuradio over UDP or TCP.
I am wondering about the data formats. As far as I was able to see with
Wireshark, for example float is 4 bytes IEEE format, but how is I and Q
arranged? Integer is 32bit wide, but again, how is it with I and Q
