Here's a flow graph that I created when I was fooling around with C4FM.

Thanks for advice Ron.What should I do for getting M-FSK signal after the Chunks to Symbols block output?Yours Sincerely.Batu Kaplan <mozbet...@gmail.com <mailto:mozbet...@gmail.com>>, 26 Nis 2019 Cum, 16:46 tarihinde şunu yazdı:Dear Marcus, Thanks for your response. First of all, it is been a while for answering your response and I am sorry about that. I could not try your solution until these days. Unfortunately, I still couldn't get over my problem on M-FSK modulation. When I try your solution, "bits to symbols and after that using frequency modulator", I managed to convert bits to integers using the packed to unpacked block. However, after subtracting data from 1.5(for M=4), that point I am stuck. Using frequency modulator will make an FSK modulated signal? If you can still help, I will be appreciated. Thanks in advance. Yours sincerely.

Convert to float, subtract 1.5, use with frequency modulator?
