3.I Can Count to 1100!


#1

I got the right answer but I just don't understand how the pattern works, can someone please explain it to me in a simple form ?


#2

there is an explanation of this in exercise 2:

8's bit  4's bit  2's bit  1's bit
    1       0       1      0 
    8   +   0    +  2   +  0  = 10

so we have 8 bits (2^3), 4 bits (2^2), two bits (2^1) and one bit (2^0, which is one bit, not zero bits)

then we can have a signal (1, aka true) or no signal (0, aka false) if we have to include the number
