Aim:
To visualize the output of decade counter on seven segment display
Apparatus required:
IC 74LS93, IC 7447 Decoder Power supply, Seven Segment Display, and Function generator
Learning Objectives:
To design a decade counter using a binary counter and display it on seven segments.
Theory:
A decade counter requires resetting to zero when the output count reaches the decimal value of 10, i.e. when 1010 and to do this we need to feed this condition back to the reset input. A counter with a count sequence from binary 0000 through to 1001 is generally referred to as a BCD binary code decimal counter because its ten state sequences are that of BCD code.
Procedure:
- Connect the circuit as given below
- Apply clock pulse of Frequency 1 Hz
- Check the output on seven segment display for every clock pulse

Conclusion:
Students will be able to learn the use of decoder and seven-segment display
Precautions:
Connect all wire connections properly and provide a proper input sequence
