Can we subtract 512 from 632? YES (Therefore diode at 512)
668 - 512 = 156
Can we subtract 256 from 156? NO (Therefore NO diode at 256)
Can we subtract 128 from 156? YES (Therefore YES diode at 128)
Can we subtract 64 from 28? NO (Therefore NO diode at 64)
Can we subtract 32 from 28? NO (Therefore NO diode at 32)
Can we subtract 16 from 28? YES (Therefore diode at 16)
28 - 16 = 12
Can we subtract 8 from 12? YES (Therefore diode at 8)
12 - 8 = 4
Can we subtract 4 from 4? YES (Therefore diode at 4)
4 - 4 = 0
As soon as we get a result of 0, we are finished and the remaining positions
are left empty (indicating a zero).
Let's check our results using this shortcut method:
On the previous page, we found the binary equal of N=44,700 was:
1 0 1 0 1 1 1 0 1 0 0 1 1 1 0 0
And, just now, we find the binary value of N to be:
1 0 1 0 1 1 1 0 1 0 0 1 1 1 0 0
We see that this way leads us to a correct result also. We could go on and
on with shortcuts and tips. For example, we can just know in our heads that
the "1" position is used only for frequencies with 5 KHz spacing. The most
important thing is simply to become comfortable and accurate in converting
N to its binary equivalent.
