Answer:
1) 10cos ( 2πfct + 10sin 2πfmt )
2) 50 watts
3) 1000 Hz
Explanation:
m(t) = 10cos(1000πt)
c(t) = 10cos(2πfct )
modulation index ( = 10
1) expression for modulated signal ( u(t) )
u(t) = Ac(cos 2πfct ) + A (cos 2πfct m(t) ) Am cos2πf mt
= 10cos 2πfct + 100 cos 2πfct cos2π500t
= 10cos ( 2πfct + 10sin 2πfmt )
2) power of modulated signal
power of modulated signal μ^2 / 2 ]
= 10^2/2 ]
= 50 watts
3) Bandwidth
B = 2fm = 2 * 500 = 1000 Hz
Okay well you first have to make sure the image you want to put in your question is somewhere in your finder for example like in pictures, documents, downloads,etc.
Next when you are typing your question you should notice that at the bottom left corner there is a paperclip. When you click on this paperclip your finder will open and then you will be able to access and download your image to your question.
Answer:
Hi there! The question is quizzing on your knowledge of type casting. Please find the explanation below.
Explanation:
The first program declares a Test class containing the main function in which two objects of class A are created and compared. The main function is the entry point of a Java program. After objects a1 and a2 are created, their comparison function “equals” is invoked and the result printed on the screen with the “System.out.println” method. The second program is the same in this respect, except for the implementation of class A. In the first program, class A has the property “x” defined as an int. The method “equals” accepts any object and type casts (converts) the passed object to a type of class A and compares and returns whether the property x of the type-casted object matches the property of the current object a. In the second program, the equals method of class A only accepts an input parameter of class A and returns whether the property x of the type-casted object matches the property of the current object a.
