Dear Prerthana, I have attached here with some m-ary visualizer graph, from it you can understand how the M-ary encoded signal look like, regarding how to generate the M-ary pulse the internal circuitry of M-ary pulse generator is not there but you may find some mathematics in the components pdf at page no. 279, the conditions are explained there very nicely. the method of generation is same as that of QAM pulse generator any other of the same kind in the library. Thanks.
Regards
