I have a pair of problems, the first two of my homework, and I'm already unclear on how finding SOP and CSOP for them work. The first:
E=xy(1+z)y'
It seems like this just reduces to 0, since 1+z is 1, and y * 1 is y, which is 0 due to y*y'. x*0 would result in 0. I don't know at what point I'm supposed to derive the SOP and CSOP from these.
The other problem I have is:
E=(x+y')(x+y)
When I factor this out, I get:
xx+xy+xy'+yy'
=x+xy+xy'+0
=x+(x*y)+xy'
=x+xy'
=x+(x*y')
=x
Once again, I don't know where I should be deriving the SOP and CSOP. Please help?
