http://web.mit.edu/6.111/www/s2004/LECTURES/l5.pdf WebThis BCD counter uses d-type flip-flops, and this particular design is a 4-bit BCD counter with an AND gate. BCD counters usually count up to ten, also otherwise known as MOD 10. Since a 4-bit counter counts from binary 0 0 0 0 to binary 1 1 1 1, which is up to 16, we need a way to stop the count after ten, and we achieve this using an AND gate ...
