Build a circuit that takes four bits as input: W, X, Y, Z. Treat WX as a 2-bit unsigned binary number, and treat YZ as a second 2-bit unsigned binary number. Your circuit should generate the output corresponding to the product of WX and YZ. You will need 4 bits of output for this problem.For example, if your input was 1011, your inputs correspond to 2 and 3. That product is 6, so your output will be 0110.Create a truth table for this problem, show all k-maps and minimizations, and build the corresponding (minimized) circuit. Use XOR, XNOR, NAND, and NOR as appropriate if it reduces the number of gates used.
We want to design a circuit that counts the number of 1s present on 3 binary inputs a, b, c and outputs that number in binary using 2 outputs y and z. For example an input of a=1, b=1, c=0 has two ones, so the output would be 210 = 102 i.e., y=1, z=0. a) Express y and z as sum of min‐terms of variables a, b and cb) Simplify the expressions for y and z using K maps.c) Draw the logical circuits for y and z using gates.
Your task is to write code to implement a two-tone siren using the QUTy. You must use one of the Waveform Outputs of TCA0 to drive the buzzer. The buzzer should always be driven with a 50% duty cycle signal. Your siren must alternate between the following frequencies: f1 = 2110 Hz with f1 active for t1 = 370 ms f2 = 4960 Hz with f2 active for t2 = 630 ms NOTE: Your programme must be interrupt driven. dc = 50% main() will call the init() function you write below and then drop into an infinite loop. The init() function you write MUST return to demonstrate your code is interrupt driven. In addition to init(), you may write any code you wish in this file, including ISRs. // NOTe: make sure to use the buffered versions of the CMP/PER registers //! NOTE: DO not use _delay_ms or _delay_us, we want you to do the math //! yourself and make your program interrupt driven in this program the buzzer should play f1 hz for t1 time, then play f2 hz t2 time, and it's play again and…
Write an 8051 C program that will monitor a temperature sensor at P1.7. When the temperature is high: i. sound a buzzer at P2.1 iii. using a delay of 250ms, blink a red LED at P2.2 When the temperature is low: i. turn off the buzzer ii. turn off the red LED
A Gray code is a sequence of binary numbers with the property that no more than 1 bit changes in going from one element of the sequence to another. For example, here is a 3-bit binary Gray code: 000, 001, 011, 010, 110, 111, 101, and 100. Using three D flip-flops and a PLA, construct a 3-bit Gray code counter that has two inputs: reset, which sets the counter to 000, and inc, which makes the counter go to the next value in the sequence. Note that the code is cyclic, so that the value after 100 in the sequence is 000.
