I have started learning multisim, i want to know how can we place dependent current source and dependent voltage source.
More importantly, how can i give digital line(stream of 0's and 1's) as input to a component ?

 

i think i got how can we place dependent current source and dependent voltage source.
now what about digital line(stream of 0's and 1's) as input or some digital pattern ??
say to a timer...say 555
