why do flip flop work because the feedback allows 2 stable states?

Draw a state diagram for:  Mealy state machine to detect the 1010 sequence. The output becomes one when you receive the sequence of 1100 and the output is zero otherwise. Overlap is allowed between the detected sequences.

I have a 24 MHz fast 8051 microcontroller, by ATMEL. It has a machine cycle of 12 clocks. Iwould like to generate a time delay of 512 microseconds (µs = 10-6). Design your timerwithout using mode 1.1. Which Timer and what mode are you going to use?2. What is the delay count and the base number of your design?3. Configure and program the TMOD register according to your design. 4. Write the assembly code of your design to program the microcontroller and generatethe 512 µs delay!

Determine if it is a Mealy or Moore state machine. Draw a state diagram. Design a circuit

4. A Normally-Open Pushbutton is used in the Micro850 PLC control system to control Lamp 1 and Lamp 2 through the PLC program as shown below. When the Pushbutton is initially not touched, the logic function that the PLC program implements can be described as Pushbutton (N.O.) Lamp 1 Rung 1 DIO DO1 Pushbutton (N.O.) Lamp 2 Rung 2 H DIO DO2 (a) Lamp 1 is always ON until Lamp 2 is ON (b) Lamp 2 is always ON until Lamp 1 is ON

What’s the difference between Moore and Mealy machines (FSM)? Design an FSM for the following sequential adder.

Q2: Level and Temperature Control of a Tank The figure below shows a sketch of an open tank that is installed in the plant of which liquid level and temperature are to be controlled. Design a typical PLC program for this control process. The sequence of operations for this system is as follow: 1. Master start/stop is also provided to shut down or start the entire process 2. To detect high and low level of liquid in the tank, two level switches are used which gives output in digital terms, that is when corresponding levels are detected, it gives output high otherwise remain low. 3. Inlet valve to control inlet process flow and outlet valve to control outlet process flow. 4. When level reaches the Level Low, Outlet flow is blocked, and inlet flow is allowed until high level is achieved. 5. A temperature sensor (NO) is used for measuring the temperature of the tanks. 6. Heating process is used to heat the material in the tank. 7. The heater is switched on when the tank is full, and the…

Design a circuit that controls the passage of a signal "A" with the specifications: 1. Output X will equal A when control B and C are the same 2. X will remain HIGH when B and C are different. Hint: Set "A" input as a CLK pin.
