Hey I would love to help with the next electrical circuit design.

I need to design a circuit that receives a 5-volt pulse of 1 micron second and emits 8 pulses at 40kHz. In addition, eight LEDs should be illuminated to indicate the pulse number transmitted. If D1-D8 are the eight diodes, only D1 should be lit when the first pulse is broadcast. The D1, D2 when two were aired and so on.

I can use the following components: 5-volt square clock with 40kHz frequency (duty cycle-50%). Beyond that, I got a hint that I should use a transistor switch as part of the realization of the circuit. I have a single 5 V supply, LM324 server amplifiers that can also be used as comparators, transistors such as 2N2222, coil capacitors and logic gates as much as I want. ICs like timer or counter must not be used. I'd love for ideas! Thank you!

Welcome to AAC!

Is this project school work?

Your posts will be easier to read if you use paragraphs to organize your thoughts. Block diagrams and/or schematics would be easier to comprehend than a wall of text.
