I need to implement a Boolean function using NOR gates only. The minimized function written as PoS is:
f(a, b, c, d) = (a+b)(a+c+d)(b+c+d')(a+c'+d')(a'+c'+d)
Now, the problem is that Hades has NOR gates that have a maximum of 4 ports, and I have 5 separate sums I need to input in the NOR gate. Any ideas how to solve this problem?
