Low-pass filters (LPFs) play a crucial role in signal processing chains by preventing aliasing, a phenomenon that can lead to distorted output. Aliasing occurs when high-frequency components in a signal are not adequately filtered, causing them to be misinterpreted as lower-frequency signals. Proper placement of LPFs in the signal processing chain is essential to ensure … Read more
Amplifiers, particularly those that operate in Class A mode, produce heat as a byproduct of their operation. This heat is a result of the electrical energy that is not converted into sound waves and is instead dissipated as heat. The amount of heat produced by an amplifier is related to its power output and efficiency. … Read more
