COUNTERS AND SEVEN SEGMENT DISPLAYS
The objectives of this experiment are:
– Examine binary and BCD counter packages.
– Cascade multiple counters for large counting sequences.
– Examine seven segment displays.
Counting in binary follows a pattern of 0’s and 1’s. The LSB changes on every number while other bits change on every other number. A counter is a circuit that forms these patterns and the first stage of the counter implements the LSB while the last stage implements the MSB. There are different types of counters namely
– Synchronous counters
– Asynchronous counters.
