Answer: False
Explanation:
Unguided medium employs an antenna for transmitting through air or vacuum.
For guided mediums the transmission is in the form of twisted copper wires, shielded twisted copper wire and optical fibres. They henceforth do not depend upon antennas for transmission through air using antennas.
Answer:
a) only one digit changes as the number increases.
Explanation:
Let us first understand what does it mean when we say only one digit changes as the number increases using the Reflected Binary code (also called Gray code)
consider the 4 bit representation of Binary coded decimal and RB codes
Decimal | Binary code | Reflected binary (RB) code
0 0000 0000
1 0001 0001
2 0010 0011
3 0011 0010
4 0100 0110
5 0101 0111
As you can see in the case of binary codes, there are more than one digit changes between two consecutive numbers.
But notice that in the case of Gray codes, there is always one digit change between two consecutive numbers.
The problem with the binary codes is that the more digits change there states the greater is the chance of ending up with random transitional values rather than real values which can be incorrect. The RB code solves this problem by only changing one digit at a time.
The RB code is widely used in linear and rotary encoders, error correction and digital logic design.
Incomplete question. I could only infer you are possibly referring to edhesive unit 8 questions. Here are a few sample questions;
1. Where does Python start?
2. To create the body of a function, we ____________ the code.
Answer:
1. Main Section
2. Indent
Explanation:
1. It is a common rule in Python programming language when coding for for it to begin at the first part of the Main Section.
2. Indenting a code involves creating space or jumping a line away from the margin of the text dialogue box, thus the code written there becomes the body of the function.
