Design a decade counter using the following 2-4-2-1 weighted code for decimal digits. Use NAND gates and T flip-flops.
Solution:
The Excitation Table of 2-4-2-1 counter is:
It can be illustrated through T Flipflops & the excitation table of T Flipflop is:
The K-Maps for input TA,TB,TC,TD & corresponding expressions obtained from K-Maps are:
From these map we obtain expressions:
& Here is the Modulo-10 counter:
