Decade Counter Circuit Diagram +9V Count Reset CLK 1 EN 2 3 4 5 6 7 8 9 R 10 4017B IC R1 1K R2 1K R3 220R CLK = Clock R = Reset 0V

Investigating the Circuit Use circuit simulation software to draw and test the decade counter circuit. What happens each time the count and reset switches are pressed? You may encounter switch bounce. What does this mean and how could you overcome it? How does this circuit differ from your programmable counter system?
