Define the following:
(1). Transducer
(2). Bandwidth.

Explanation

### Step-by-Step Solution:

1. **Define Transducer**:
- A transducer is a device that converts one form of energy into another. In the context of electronic communication, transducers play a crucial role in the conversion of signals. For example, a microphone (mic) is a transducer that converts sound energy (acoustic energy) into electrical energy (electrical signal). This conversion is essential for transmitting information in communication systems.

2. **Define Bandwidth**:
- Bandwidth refers to the range of frequencies over which a particular device or system operates effectively. It can be defined as the portion of the frequency spectrum that is occupied by a signal. In communication systems, bandwidth is a critical parameter as it determines the data transmission capacity of the system. A wider bandwidth allows for the transmission of more data within a given time frame.
