Digital Logic design: How to build the circuit

Building Parking Lot You are building a digital system that keeps track of your new parking deck's capacity. Assume the capacity of the deck is 40 vehicles. Cascade two of your mod-16 counters. The circuit should have following features: 1. Counting up/down between 0 to 40. Use a RC debouncing switch given below to avoid bouncing 2. An LED to indicate when the parking deck is completely full at 40 vehicles 3. Disable counting up when the parking lot is full 4. Show the total number of vehicles in the deck using LEDs (7-Seg display is an extra credit) 5. Provide schematic showing the gates, IC numbers and pin numbers that were actually used in building the circuits 6. Discuss each circuit, including your observations of any problems encountered in designing or building the circuits and comment on the problems and your idea to solve the issues +5v 10k2 open Schmitt Inverter close 1 open 100 74LS14 Switch F Switch open:T C(R+Ra)-10.1ms closed Switch closed: TC(R)0.mS RC Switch Debounce Circuit
