Amplification refers to the process of increasing the magnitude or strength of a signal, such as sound or electrical signals, in order to enhance its intelligibility or detectability. Amplification is commonly used in various fields, including electronics, acoustics, and telecommunications. It involves the use of amplifiers, which are electronic devices that increase the amplitude of a signal while maintaining its waveform. Amplification can be used to boost the power of audio signals in sound systems, improve the transmission of data in telecommunications networks, or enhance the sensitivity of sensors in scientific instruments.
