Computer Logic Training Board on Synchronous and Asynchronous Counter has been specifically designed to give students an idea about Synchronous and Asynchronous Counter and to study of Synchronous and Asynchronous Counter. The output of the Synchronous and Asynchronous Counter can be observed with the help of logic level indicators (LEDs), which are provided on the panel. The board is absolutely self contained and requires no other apparatus. Practical experience on this board carries great educative value for Science and Engineering Students.

The board consists of the following built-in parts :
1. +5V D.C. at 100mA, IC regulated power supply.

2. 4 Nos. Input Switches for data input.

3. IC For Synchronous Counter 74193 is provided on board with Combinational Circuit.

4.  IC For Asynchronous Counter 74190 is provided on board with Combinational Circuit.

5.  Two 2 Input Or Gate is provided on board using 7432

6. Four 2 Input And Gate is provided on board using 7408

7. One 3 Input Nand Gate is provided on board using 7410

8. Two 3 Input And Gate is provided on board using 7411

9. Four JK Flip- Flop are provided using 7476 IC.
10. 5 Output LEDs with driver circuit to observe the Output .

11. A Pulser to provide the pulses manually for triggering.

12. Adequate no. of other Electronic Components.
13. Mains ON/OFF switch, Fuse and Jewel light.
