Which among following is not a basic terminology used in electronic communication systems?

Options

A. Transducer
B. Transmitter
C. Telegraph
D. Attenuation

Answer

To determine which among the following is not a basic terminology used in electronic communication systems, let's analyze each option provided:

1. **Transducer**: A transducer is a device that converts one form of energy into another. In the context of communication systems, it is used to convert signals from one form (like sound) to another (like electrical signals). Therefore, transducer is a basic terminology used in electronic communication systems.

2. **Transmitter**: A transmitter is a device that sends out signals, typically in the form of electromagnetic waves. It plays a crucial role in communication systems by transmitting information over distances. Hence, transmitter is also a basic terminology used in electronic communication systems.

3. **Attenuation**: Attenuation refers to the reduction in strength of a signal as it travels through a medium. This concept is essential in communication systems as it affects the quality and clarity of the transmitted information. Therefore, attenuation is a basic terminology used in electronic communication systems.

4. **Telegraph**: The telegraph is a historical method of communication that transmits messages over long distances using electrical signals. However, it is not a terminology used to describe components or processes within electronic communication systems. Instead, it is an example of a communication system itself.

Based on the analysis above, the option that is **not a basic terminology** used in electronic communication systems is **telegraph**.

**Final Answer**: Telegraph
