1. Write the full equations to light the bottom segment of a 7-segment display. INLCUDE the hexadecimal digits too ( b, c, d, and E ). Then simplify the equations using a k-map and draw the final circuit.
2. Draw a CMOS circuit for an S-R flip-flop.
3. Explain the basic operation of a CMOS transmission gate and compare it to a tri-state buffer. There is one important difference, make sure to explicitly discuss that difference.
4. Design a 3-bit counter using D flip-flops to cycle through the following sequence: 010, 101, 110, 001. Make sure the counter is self-starting.
