With an Arduino Uno:

Using 2 external buttons b0 and b1 to represent ‘0’ and ‘1’, design a sequence detector to detect a pattern “1101”. An LED lights up once, when the sequence “1101” occurs.

how do i use a sinewave with 5V peak to peak at 10kHz from a function generator to observe it's spectrum on the analyzer. do I have to build a circuit to make a sinewave or can i just use the oscilloscope and function generator without a circuit being built? if so which kind of circuit can I build to make a sinewave with 5V peak to peak.

Design a limiter circuit such that a ±20 V input sinusoidal wave is limited between +5 V and –3 V at the output. Use a single current limiting resistor and specify its value such that no diode experiences a current greater than 10 mA.

what will happen to Insertion loss if we change the structure of a filter from lumped to distri ?
what will happen to return loss if we change the structure of a filter from lumped to distri ?

What supports the notion that the product of resistance and capacitance is the time constant for an RC circuit?

Matlab

The following matrix describes Injury Severity Score (ISS, unitless) and hospital stay (days). Row 1 is the ISS and row 2 is the hospital stay.

[64,35,50,46,59,41,27,39,66;

8,2,5,5,4,3,1,4,6].    

Create a script that plots stay in hospital vs ISS. Label the plot and all axis. Display to the command window a message with the mean ISS score, and the mean days in hospital. (i.e. “The mean ISS score is 30”, not just x = 30).

Use the sort(x) to arrange a vector in ascending order

Question: On the plot select “Tools” -> “Basic Fitting”. A window will pop up for line fitting. Select the box “linear”. Press the right arrow button to get the coefficient values for linear fit. What is the estimated stay for a patient with a ISS of 55?

Make note of the formula as it will be used later.

Calculating ISS for an individual involves taking scores from an Abbreviated Injury Scale (AIS) from 0 – 5 for six different body areas head, face, chest, abdomen, extremities, and external. The three body areas with the highest score have their AIS squared and are added together to produce an ISS for individual.

Do Not Use Pseudo Insturctions or li la instructions, etc...

Write and test a MIPS program consisting of four functions. In the following descriptions, the symbol & means “address of”.

void main(): The main function must 1) print your name 2) call the readData function 3) call count function 4) complete the program. The main function must set up all parameters before calling each of the functions.

int readData (&array): The starting address of an array is passed to the function as a parameter using $a0. The function must prompt for and read and store integers in the array until either a zero is entered or 10 numbers are read. Once the tenth integer is entered, your program must stop reading. The function must return (using $v0) the number of values read and stored in the array (10 or less). The zero input is not part of the array and must not be stored in the array. If the first input is a zero, then the array will be empty and the count returned is zero.

float average (&array, count): The starting address of an array (in $a0) and the number of integers stored in the array (in $a1) are passed to the function. The purpose of the function is to calculate and return (using $f0) the floating point average of the numbers. To find the average, sum all the integers together and then divide by the count as a floating point value. If the count is zero, return 0.0. Use appropriate registers for the parameters and the return value.

void count (&array, count): The starting address of an array (in $a0) and the number of integers stored in the array (in $a1) are passed to the function. The function determines how many of the integers in the array are greater than or equal to the average. First the parameters for the average function are set and then average function is called to determine the average value. The returned value is then printed. Then each value in the array is tested to determine if its value is greater than or equal to the average. The count of the values greater than or equal to the average is then printed.

Example input and output:

Linda Chatting
Enter a number 3
Enter a number 6
Enter a number 2
Enter a number 4
Enter a number 0
The average is 3.750000000
There are 2 numbers greater than or equal to the average.

In addition,

 Functions must be called using jal and return using jr.

 Parameters must be passed as specified and used correctly. The readData, average and count

functions must access the array through the parameter, not directly.

 Be sure to comment all instructions. All functions must include comments describing the

function and its parameters and return value (if any). Be sure that your name and class ID appear at the beginning.
