Basic components of a transmitter are:

Options

A. message signal generator and antenna
B. modulator and antenna
C. signal generator and modulator
D. message signal generator, modulator and antenna

Answer

To identify the basic components of a transmitter, we can break down the problem into a series of logical steps:

### Step-by-Step Solution:

1. **Understanding the Function of a Transmitter**:
- A transmitter's primary function is to send information from one point to another. This involves generating a signal that can be transmitted over a communication channel.

2. **Identifying Basic Components**:
- The basic components of a transmitter typically include:
- **Message Signal Generator**: This component generates the original information signal that needs to be transmitted. It could be audio, video, or any other form of data.
- **Modulator**: The modulator is essential for modifying the message signal so that it can be effectively transmitted over the communication channel. It combines the message signal with a carrier wave to create a modulated signal.
- **Antenna**: The antenna is used to radiate the modulated signal into the communication channel (like air or space) so that it can reach the receiver.

3. **Conclusion**:
- Therefore, the basic components of a transmitter are:
- Message Signal Generator
- Modulator
- Antenna

4. **Final Answer**:
- Based on the above components, the correct option that lists these components would be the one that includes the Message Signal Generator, Modulator, and Antenna.
