Question

'Bandwith' is related with:

• A. Electronic path which determines how many cycles.
• B. Methods of digital transmission
• C. Define the number of bits.
• D. Frequency modulation

Hint:

Think of bandwidth as the "width" of the electronic pipe. A wider pipe can carry a wider range of frequencies (more cycles), which in turn allows for more data to be sent per second.

Answer 1

The Correct Option is A

Step 1: Define Bandwidth. Bandwidth (correcting the typo 'Bandwith') has two main meanings: In analog signals, it is the difference between the upper and lower frequencies in a continuous set of frequencies, measured in Hertz (cycles per second). In digital communication, it is the maximum rate of data transfer across a network path, measured in bits per second. The analog definition is the foundational one.

Step 2: Analyze the options. \[\begin{array}{rl} \bullet & \text{(A) "Electronic path which determines how many cycles." This directly relates to the analog definition of bandwidth – the capacity of a path measured in cycles per second (Hertz). This is the most technically accurate foundational definition.} \\ \bullet & \text{(B) "Methods of digital transmission" is too broad.} \\ \bullet & \text{(C) Bandwidth determines the rate of bits, but does not "define the number of bits" in a message.} \\ \bullet & \text{(D) "Frequency modulation" is a technique that uses bandwidth, but it is not the definition of it.} \\ \end{array}\]

Step 3: Conclude. Option (A) provides the best physical description of what bandwidth represents at its core.
