Hi Marcus,
Thank you very much for
introducing me with "Screenshot" option in
GRC :) I checked the provided link and what
I understood is that the file sink is saving
bits correctly but in a different format (32
bits for floating point data). However, I
have few confusions:
1. The ASCII equivalent of "#"
or "?" is not equal to "1010" so why the
saved data is "##??" ?
2. In-order to further
comprehend this concept, I designed a DPSK
MOD/De-MOD using GRC DPSK blocks as shown
in DPSK_loopback image. The data "1010" is
provided via file source shown in Data_Tx
image and demodulated data is saved using
file sink. To my surprise, the demodulated
data is successfully saved in desired Byte
format in file i.e. "101010" as shown in
Rx_Data snapshot.
3. To verify this, I designed an
another design, which just takes the same
data from file and converts it into "10" and
save back to file as shown in Data_save_try.
But this time, the saved file format was
unrecognizable and the file didn't even
opened as shown in Rx_file.
My application requires to
display and save the "Telemetry data" coming
from a Satellite in binary form i.e. 1010
etc as happening in DPSK_loopback. How
should I achieve this in my design shown in
my previous email?
Need your expert opinion :)
Best Regards
Salman
