HELLO JYOTI..
As far as your query is concerned well there is a difference between using fork and splitter in your design…if you want your signal to be duplicated without any loss then its better to use fork…and in other case the term split itself suggests that the signal is splitted…
it splits the signal power and also losses are associated when using a splitter..
I hope u understand the difference.. hope it helps you..
Thanks & regards
