Amplifiers and Linear
Power amplifier is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape with a larger amplitude.
Amplifiers applications include:
- Audio Amplifiers
- Differential Output Amplifiers
- High Speed Amplifiers
- Low Noise Amplifiers
- Operational Amplifiers
- Programmable Gain Amplifiers
- Variable Gain Amplifiers
- Video Amplifiers
A linear system is a mathematical model of a system based on the use of a linear operator. Linear systems typically exhibit features and properties that are much simpler than the general, nonlinear case. As a mathematical abstraction or idealization, linear systems find important applications in automatic control theory, signal processing, and telecommunications. For example, the propagation medium for wireless communication systems can often be modeled by linear systems.
