Design a BCD counter. The circuit counts from 0 to 9, then resets back to 0 to restart the counting sequence. The circuit has one input run/stop. If the input

is 1, the counter will count. If the input is0, the counter will freeze in its current location until the input is set to 1 again. III IUSI agal• The circuit has one output. It becomes 1 when the counter completes a cycle and starts the next one. Otherwise, that output is 0.
