We first looked at the families of the logic families , which was very informational , next we also learned how to write combinational equations based on the circuit. Lastly we reviewed the 7 main logic gates and also the binary conversions , all of these concepts was really helpful for me to apply my analytical skills on solving digital circuits. We also looked at also how to interface different types of circuit like TTL pull up and pull down . Mainly we learned how to solve combinational circuits . This helped me in one way mainly to interface many actuators and sensors to my final design project . The 7 main logic gates helped me to understand how each gates work and how you can apply each logic gate in each circuit to get a different output.
