Hello,
I understand that I have use online ASCII to binary converter and for
that I am using below online converter.
https://www.rapidtables.com/convert/number/ascii-to-binary.html
<https://www.rapidtables.com/convert/number/ascii-to-binary.html>
But I am facing an issue, while I am transmitting repetitive pattern
such as 1100, 1010 , the data stored in the file after mod-demod is
almost similar( only some initial bits are changed) . Please check the
screenshot attached.
But when I am transmitting some random pattern instead of repetitive
using file source, I am not receiving the same pattern, while I am
converting the stored ASCII to binary using converter.
I have sent the GRC file in previous mail. Kindly let me know, where
is the problem?
Waiting for your positive response.

Hi Maitry - if by update you mean dumping a binary file as binary
instead of hexadecimal, then on Linux use
xxd -b <infile> <outfile>

Hello,
Please find attached grc file for reference. I have done trial
and error by converting the output file into online ascii to
binary converter, but it provides random output.
Please guide which binary viewer I need to use in check the
data in 1 and 0 format(binary) ?

Hello Maitry,
The File Sink is not producing a text file, it is the raw
binary data.
You need to look at the contents of the file using a
binary viewer.

Derek
