The impulse response of a discrete-time LTI system is
h(n) = 2δ(n) − δ(n − 4).
Find and sketch the output of this system when the input is the step function
x(n) = u(n).

Design a half adder using mux and implement using SMART LOGIC simulator software

How many of the unsigned numbers in a string are a multiple of 10
Write the assembly code that finds and saves the indexes of these numbers in another array.
Example for variables DIZI, ON_KAT and ON_IND in the data segment part below
definitions are given. Data must be in DW type. Other variables as needed
You can define.
DIZI DW 9, 55, 100, 132, 140, 63, 17, 95, 30
ON_KAT DW 0
ON_IND DW 50 DUP (?)
At the end of running the program you wrote for the above variable values, ON_KAT and
ON_IND variables must take the following values.
ON_KAT: 3
ON_IND: 2, 4, 8

In the Fibonacci number sequence, the first 10 of which are given below, each number is
is equal to the sum of two numbers. The first two numbers are equal to one.
1, 1, 2, 3, 5, 8, 13, 21, 34, 55,…
FIB_NUM variable defined below gives the number of fibonacci to be calculated. First FIB_NUM
Write the assembly code that records the number of fibonacci numbers into the FIB_LIST variable.
Data must be in DB type. If required, you can define other variables.
FIB_NUM DB 10
FIB_LIST DB 50 DUP (?)
At the end of the program you wrote for the above variable values, FIB_LIST
The first 10 bytes of field of the variable should be as follows.
FIB_LIST: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55

Two port networks are described in matrices form [

B) calculate the gradient at and
C) differentiate and calculate the value of at and
D) compare your answers with part b and part c
E) calculate the second derivative of the instantaneous voltage

design and implement sequential circuit which executes the following function in logisim. there are four lamps at the output. first, first lamp is turned on and it waits 4 clock cycles. then first lamp is turned off and second lamp is turned on and it waits for 5 clock cycles. this way it continuous with 6 clock cycles for third and 7 cycles for fourth lamp. at the end it returns to the first lamp and repeats the same steps. each time the count number should be shown by 7-segment display. you need to submit it as .circ file with your name and surname. below is given an example architecture to design the circuit: lamp selector increment 12 lamp 1 lamp 2 counter combinational control logic decoder lamp 3 restart lamp 4 7-segment display o
