Assignment:
Using positive edge-triggered D-type bistables with clear and preset terminals (74LS74) and some logic, design a MOD-6 ripple-up (0,1,2,3,4,5,0...) counter that can also be manually reset with an external push button.
1. Draw the circuit block diagram, labelling the LSB & MSB.
2. Ignoring the generation of glitches, briefly explain how the circuit works.
3. Draw the count sequence showing the effects of propagation delay.
Provide complete and step by step solution for the question and show calculations and use formulas.
