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

Options

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

Answer

To solve the question, we need to identify which option is not a basic terminology used in electronic communication systems. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Components of a Communication System
- A communication system typically consists of several key components:
- **Sender**: The entity that sends the information.
- **Transducer**: A device that converts the information from one form to another (e.g., from sound to electrical signals).
- **Transmitter**: The component that sends the signal through a channel.
- **Channel**: The medium through which the signal travels (e.g., air, cables).
- **Receiver**: The entity that receives the transmitted signal.
- **Another Transducer**: Converts the received signal back into a usable form.

### Step 2: Identify the Options
- The question likely provides several options, one of which is "telegraph." We need to evaluate whether each option is a basic terminology used in electronic communication systems.

### Step 3: Analyze the Options
- **Telegraph**: This is a historical communication device that transmits messages over wires. While it is a method of communication, it is not a basic terminology that describes the components or processes of modern electronic communication systems.
- Other options (not provided in the question) may include terms like "transmitter," "receiver," "signal," etc., which are indeed basic terminologies.

### Step 4: Conclusion
- Based on the analysis, the term that does not belong to the basic terminologies of electronic communication systems is "telegraph."

### Final Answer
- The answer to the question is **telegraph**.
