The program allows the transmission of digital signals in the form of line codes (NRZ,RZ,AMI,HDB3, BnZS, CMI, Manchester) or modulation signal (ASK, FSK, PSK, M-PAM, M-QAM, MSK,...). Using Rcosin filter or IIR Filter, and Furrier . spectral analysis. This is real transmitted signal not simulations. The users can see or touch by using OsiloScope.
This is free Version so set some limitations: maximum 50bits, and Sample Frequency <8000Hz, and Modulation level <=4. And user can not zoom in screen by touch

The program was introduced into teaching digital information at Hanoi University of Science and Technology
