Signal recovery lock in amplifier
WebSignals with a frequency f above fc will appear at a frequency 2fc−f. This phenomenon is called aliasing. To avoid this problem, A/D conversion is usually preceded by an analog … WebMar 24, 2024 · Lock-in amplifiers are intended for a low-amplitude useful signal recovery from noise, whose amplitude is hundreds and thousands of times higher. With this purpose, the input signal is amplified and multiplied by a reference signal, the frequency of which equals the frequency of the useful signal.
