Time-varied gain

Time-varied gain refers to a technique used in signal processing, telecommunications, and various fields involving dynamic control of signal amplitude over time. Essentially, it involves adjusting the gain (amplification or attenuation) of a signal in a time-dependent manner. ### Applications: 1. **Audio Processing**: In audio engineering, time-varied gain can be used for effects like compression and expansion, where the loudness of certain audio signals is adjusted dynamically based on the amplitude of incoming signals.
