Low-gain refers to a type of amplification or signal processing where the output signal is only slightly increased compared to the input. This is often used in audio equipment, such as microphones and amplifiers, to maintain sound quality while avoiding distortion. Low-gain settings help capture subtle details without overwhelming the original signal. In electronics, low-gain circuits are designed to provide a gentle boost to signals, making them suitable for applications like sensor readings or data transmission. These circuits ensure that the integrity of the original signal is preserved, which is crucial in various fields, including telecommunications and audio engineering.
