In digital electronics and modern computer hardware, a flip-flop is sequential digital circuit used as a basic memory element. It has two stable states and can be used to store state information. One of its states represents ‘1’ while the other represents ‘0’. The most common types of flip-flops are SR-flip-flop, JK-flip-flop, and D flip-flop. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs).

Q1 a) Design a single-digit decade counter that counts from 0 to 9 and repeats. The single-digit decade counter should be built by a cascaded synchronous binary counter (74LS163) and other basic logic gates. Simulate the complete counter circuit by OrCAD and PSPICE. Capture the circuit schematic and the simulated waveform. (Define the simulation timings for at least one full counting cycle from 0 to 9 and back to 0.)

Part III Design and implement a circuit that successively flashes digits 0 through 9 on the 7-segment display HEXO. Each digit should be displayed for about one second. Use a counter to determine the one-second intervals. The counter should be incremented by the 50-MHz clock signal provided on the DE-series boards. Do not derive any other clock signals in your design-make sure that all flip-flops in your circuit are clocked directly by the 50-MHz clock signal. A partial design of the required circuit is shown in Figure 2. The figure shows how a large bit-width counter can be used to produce an enable signal for a smaller counter. The rate at which the smaller counter increments can be controlled by choosing an appropriate number of bits in the larger counter. Counter 50 MHz Clock Counter ...

Develop a logic circuit necessary to meet the following requirements: In a certain chemical-processing plant, a liquid chemical is used in a manufacturing process. The chemical is stored in three different tanks. A level sensor in each tanks produces a HIGH voltage when the level of chemical in the tank drops below a specified point. Design a circuit that monitors the chemical level in each tank and indicates when the level in any two of the tanks drops below the specified point. The design must include a chip with logic gates and also be written with VHDL code.
