A push-pull configuration is a type of electronic circuit design commonly used in amplifiers. In this setup, two active devices, such as transistors or tubes, work together to amplify a signal. One device pushes the signal while the other pulls it, allowing for greater efficiency and reduced distortion in the output. This configuration is often found in audio equipment and power amplifiers, where it helps to deliver a strong and clear sound. By alternating the roles of the devices, the push-pull design minimizes the heat generated and improves overall performance, making it a popular choice in various electronic applications.
