In various fields, "conversion" can refer to different processes. However, if you're asking about electrical engineering, particularly related to signal or power conversion, there are two primary types of conversion:
### 1. **Signal Conversion**
**Signal Conversion** involves changing a signal from one form to another, typically between analog and digital formats. This can be further divided into:
- **Analog-to-Digital Conversion (ADC):** This process converts an analog signal, which varies continuously, into a digital signal, which is a discrete representation. ADCs are used in applications like digital audio recording, digital signal processing, and more.
- **Digital-to-Analog Conversion (DAC):** This converts a digital signal back into an analog signal. DACs are used in devices like digital music players, televisions, and any system that outputs analog signals from digital sources.
### 2. **Power Conversion**
**Power Conversion** involves changing electrical power from one form to another, often to meet the needs of specific applications. This can include:
- **AC-to-DC Conversion (Rectification):** This converts alternating current (AC) from the power supply into direct current (DC), which is used by many electronic devices and circuits. This process is typically performed using a rectifier.
- **DC-to-AC Conversion (Inversion):** This converts direct current (DC) into alternating current (AC). Inverters are used in various applications, including renewable energy systems like solar panels and backup power systems.
Both types of conversion are fundamental in modern electronics and electrical engineering, facilitating the functionality and efficiency of various devices and systems.
