Electrical Engineering XYZ MCQs
Digital signals are transmitted through a single conductor in:
- Serial
- Parallel
- Analog
- None of the above
Correct answer: 1. Serial
Explanation: When digital signals are transmitted through a single conductor, it is typically done serially. In serial transmission, data is sent bit by bit over a single wire or channel. This is in contrast to parallel transmission, where multiple bits are sent simultaneously over multiple wires or channels.
In serial transmission, each bit is sent sequentially, one after the other, making it suitable for transmitting data through a single conductor. This method is commonly used in various communication protocols, such as RS-232, USB, and Ethernet, among others.
Parallel transmission, on the other hand, requires multiple conductors to transmit data simultaneously, which is not applicable when transmitting through a single conductor.
Analog transmission involves the continuous representation of data, rather than discrete digital signals, so it is not applicable when discussing the transmission of digital signals.
Therefore, the correct answer is “Serial”.
