An analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. Using the Sampling Theor

em, what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation?
If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps?

Give your answer in scientific notation to 1 decimal place.

Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels

Answer:

3.2*10^5

Explanation:

By Nyquist's theorem we must have 2*14.5kHz=29kHz so 29,000 samples per second. 2048=2^11 so we have 11 bits per sample. Finally we have 29000*11 bits per second (bps) =319000=3.2 * 10^5

MrMuchimi

According to Henri Fayol, it can be said that there are five functions of management: planning, organizing, staffing, directing, and controlling. From the description in the question, it seems that Susan should employ the controlling management function – which is defined as ensuring that all the ongoing process are proceeding as planned.

It is clear that this definition is precisely what Susan needs to do to fulfill the request that she was given.

Two numbers are given (numbers are entered from the keyboard). If both numbers are positive, then output their sum, if both numb
AleksAgata [21]

Answer:

The program in Python is as follows:

num1 = int(input())

num2 = int(input())

if num1 >=0 and num2 >= 0:

   print(num1+num2)

elif num1 <0 and num2 < 0:

   print(num1*num2)

else:

   if num1>=0:

       print(num1**2)

   else:

       print(num2**2)

Explanation:

This gets input for both numbers

num1 = int(input())

num2 = int(input())

If both are positive, the sum is calculated and printed

<em>if num1 >=0 and num2 >= 0:</em>

<em>    print(num1+num2)</em>

If both are negative, the products is calculated and printed

<em>elif num1 <0 and num2 < 0:</em>

<em>    print(num1*num2)</em>

If only one of them is positive

else:

Calculate and print the square of num1 if positive

<em>    if num1>=0:</em>

<em>        print(num1**2)</em>

Calculate and print the square of num2 if positive

<em>    else:</em>

<em>        print(num2**2)</em>

B. Find Addition of Binary Numbers: 1100112 + 11012
schepotkina [342]
Hello, I assume you mean 110011_2 + 1101_2

To add 110011+ 1101 we can setup the problem like the following:

   110011
+     1101 
-------------
  1000000

When we add 1 + 1 this equals 10 so we just carry the 1 and we keep doing that from right to left. Also 1 + 0 = 1

PLEASE BE CONFIDENT ABOUT YOUR ANSWER
Zigmanuir [339]

Answer: d. should be lowercase.

Explanation:

ID attributes are case sensitive for the most part - DOM and Java Script - which means that the ID attribute does not always have to be lowercase.

It can be uppercase as well. ID attributes can also start with a number and as of HTML 5 can start with a special character as well. Finally, the ID attribute must always be unique within each document.
