- To drive an external actuator we need to provide an analog periodic signal y, defined as follows, y=1.5+1.5*cos(2*pi*f*t) , f=20 Hz. Your task is to generate this signal using a 16-bit digital-to-analog converter peripheral (DAC16). Answer the following questions. A. What is the maximum and minimum output voltage at the analog output? Fill in the table below by specifying min/max values and times when those values are achieved. Min/Max Value [Volts] Time [milliseconds] Min Max B. What is duration of one period of the signal y in milliseconds? What is the frequency of y? C. Let us assume that we provide a lookup table with only 10 samples for a single period of the signal y? Fill in the following table with the values for the first 4 samples (assume the first sample starts at t=0). Assume reference voltages VR+ = 3.5 V and VR- = 0V Sample t=?

When the temperature exceeds the safety threshold value, this will set the sensor ON which is connected to the input port of a microcontroller. The relief valve itself is connected to the output of the microcontroller. The safety system should work as described below: 1. The temperature sensor is connected to Port B, bit 3 of the microcontroller 2. The relief valve is connected to Port A, bits 1 and 2 of the microcontroller 3. When the temperature in the furnace exceeds the threshold value, the sensor sets the input port B, bit 3 to ON. 4. When the sensor is ON, the microcontroller sends an appropriate output to Port A inorder to open the coolant relief valve. 5. As soon as the sensor goes to the OFF state, the microcontroller clears all the output port bits thus closing the relief valve. Q1. A flowchart can be used to describe the step-by-step plan…arrow_forwardYou have an AVR ATmega16 microcontroller, one yellow LED, and one bicolor LED. Write aprogram to make the bicolor LED start out green for 3 seconds (connected at I/O pin PB0). After 3seconds, change the bicolor LED to red (connected at I/O pin PB1). When the bicolor LED changesto green, flash the yellow LED (connected at I/O pin PB2) on and off once every second for tenseconds. When the yellow LED is done flashing, the bicolor LED should switch back to red andstay that way.arrow_forward
- Assume we are writing a testbench for a sequential circuit that has three control inputs (cA, cB, cC) and a periodic clock (clk). If we define CLK_PERIOD as a localparameter with a value of 50 (nsec), write the testbench segment that would ensure all possible combinations of the control inputs were tested on a clock rising edge. This is can be done more elegantly if you define each time step in terms of the constant CLK_PERIOD. Your answer should include the statements that define clk, cA, cB, and cC over time. Hint: think of how you would show all combinations of three variables on a truth table and replicate that over time, where each combination is held over a timespan with a clock triggering edge.arrow_forwardWrite a VHDL code to implement a shifter which shift right 4 bits of information.arrow_forwardApply 5B: Use a 7-Segment Decoder to Drive a 7-Segment Display 1. Draw the wiring diagram of the 74LS47 device driving the common-anode 7-segment display through 3300 resistors in series, one per segment. 2. Build the circuit based on the wiring diagram. Tie off any control inputs of the 74LS47 device to enable it as a 7-segment decoder. Test all the segments of the display by temporarily connecting LT (pin 3 of 74LS47) to GND. Then connect D, C, B, and A of the 74LS47 device to power or ground rail and cycle through the 16 combinations to verify that the display shows the characters according to the truth table of the 74LS47 device. 3. Now interface the circuit in Apply 5A.4 with the circuit in Apply 5A.2 such that the display only shows the numbers controlled by N3N₂N₁No that are prime. When the numbers are non-prime, the display should be blank. Hint: use a single device with basic gates.arrow_forward

Start the count at 0x00 and stop the count at 0xFF+1.

You need to add a bit named "M" for the excitation table that helps it switch between up and down mode and draw the state transition diagram, excitation table, k-map and circuit diagram with T-flip flops. When M = 0, it will perform up counter. When M = 1, it will perform down counter.arrow_forward3.

- Using Logism for otherwise complete the attached 8 bit alu The Arithmetic Logic Unit The most important and possible most difficult component to implement is the arithmetic logic unit. Thefunctions of the ALU are shown in Table 1. The ALU should have 5 inputs (A-input, B-input, F0-input, F1-input, Finput) and 1 output (C-output). You will need to determine how many bits each input and output should have.Remember, you are designing an 8-bit microprocessor! . For example, to add the value on the A-bus8-bit ALUto the value on the B-bus, you can simply use an 8-bit adder. Explore the components in Logisim! Additionally,you can think about using a multiplexer to determine which ALU function will be performedarrow_forwardWrite Mnemonics in SIM 8085.

Now consider using FCLA to support 256-bit additions. How many levels will there be in your design? Why? Using gate delay as the unit of time, how many gate delays are needed for your 256-bit adder to output the carryout from its MSB?arrow_forward
